2 Chapter Overview Recognizing Different Perspectives on Quality
What is Quality? Differing Functional Perspectives on Quality The Three Spheres of Quality Other Perspectives on Quality Arriving at a Common Understanding of Quality using a Contingency Perspective of Quality

3 Recognizing Different Perspectives on Quality
There are many different definitions and dimensions of quality. For the present, you should view quality as a measure of goodness that is inherent to a product or service. Employees working for the same firm often view quality differently as illustrated in the next slide. Perceptions on Quality Can Vary In order to communicate effectively about quality, managers need to recognize that differences in perceptions of quality exist.

4 What Is Quality? Garvin’s Definitions of Quality
David Garvin of the Harvard Business School found that most definitions of quality were either transcendent, product-based, user-based, manufacturing-based, or value-based. Garvin’s Dimensions of Product Quality Using the five definitions of quality, Garvin developed a list of eight quality dimensions. Service Quality Dimensions Parasuraman, Zeithamel, and Berry of Texas A&M University published a widely recognized set of service quality dimensions.

5 Garvin’s Definitions of Quality Slide 1 of 2
Transcendent Definition Quality is something that is intuitively understood but nearly impossible to communicate such as beauty or love. Product-Based Definition Quality is found in the components and attributes of a product. User-Based Definition If the customer is satisfied, the product has good quality.

6 Garvin’s Definitions of Quality Slide 2 of 2
Manufacturing Based Definition If the product conforms to design specifications, it has good quality. Value-Based Definition If the product is perceived as providing good value for the price, it has good quality.

7 Garvin’s Product Quality Dimensions Slide 1 of 3
Performance Features Durability Reliability Serviceability Conformance Aesthetics Perceived Quality

8 Garvin’s Product Quality Dimensions Slide 2 of 3
Performance Refers to the efficiency with which a product achieves its intended purpose. Features Attributes of a product that supplement a product’s basic performance. Reliability The propensity for a product to perform consistently over its useful design life. Conformance Numerical dimensions for a product’s performance, such as capacity, speed, size, durability, color, or the like.

9 Garvin’s Product Quality Dimensions Slide 3 of 3
Durability The degree to which a product tolerates stress or trauma without failing. Serviceability Ease of repair. Aesthetics Subjective sensory characteristics such as taste, feel, sound, look, and smell. Perceived Quality Based on customer opinion. Customers imbue products and services with their understanding of their goodness.

10 Service Quality Dimensions Slide 1 of 3
Parasuraman, Zeithamel, and Berry’s Service Quality Dimensions Tangibles Responsiveness Service Reliability Assurance Empathy

11 Service Quality Dimensions Slide 2 of 3
Tangibles Include the physical appearance of the service facility, the equipment, the personnel, and the communication material. Service Reliability Differs from product reliability in that it relates to the ability of the service provider to perform the promised service dependably and accurately. Responsiveness The willingness of the service provider to be helpful and prompt in providing service.

12 Service Quality Dimensions Slide 3 of 3
Assurance The knowledge and courtesy of employees and their ability to inspire trust and confidence. Empathy Caring, individual attention paid to customers by the service firm.

13 Why Does It Matter That Difference Definitions of Quality Exist?
Understanding that definitions and dimensions of quality exist allows measures to be taken to provide a better basis for communication and planning in a firm.

14 Differing Functional Perspectives on Quality
Engineering Perspective Operations Perspective Strategic Management Perspective Marketing Perspective Financial Perspective Human Resources Perspective

15 Engineering Perspective on Quality Slide 1 of 4
Nature of Engineering Perspective Engineers are interested in applying mathematical problem solving skills and models to the problems of business and industry. Two of the major emphases in engineering Product design Process design

16 Engineering Perspective on Quality Slide 2 of 4
Product Design Engineering Involves all of those activities associated with developing a product from concept development to final design and implementation. Product design life cycle Key to quality as quality is assured at the design stage. Concurrent engineering The simultaneous performance of product and process design activities. Has resulted in improved quality and faster speed to market for new products.

Product Design Life Cycle Figure 1.1 Idea Generation Prototype Iterations Preliminary Design Prototype Development Final Definition Product Design & Evaluation Implemen- tation

18 Engineering Perspective on Quality Slide 4 of 4
Related Concepts Life Testing Is a facet of reliability engineering that concerns itself with determining whether a product will fail under controlled conditions during a specified life. Redundancy Is applied so that a back up system can take over for the failed primary system. Statistical Process Control Is concerned with monitoring process capability and process stability.

19 Operations Perspective on Quality Slide 1 of 6
Nature of Operations Perspective The operations management view of quality is rooted in the engineering approach. Like engineers, operations managers are very concerned about product and process design. However, rather than focusing on only the technical aspects of these activities, operations concentrates of the management of these activities. Operations management has developed into an integrative field, combining concepts from engineering, operations research, organizational theory, organizational behavior, and strategic management.

20 Operations Perspective on Quality Slide 2 of 6
Systems View Operations management utilizes the systems view to address quality problems that underlies modern quality management thinking. The systems view involves the understanding that product quality is the result of the interactions of several variables such as machines, labor, procedures, planning, and management.

21 Operations Perspective on Quality Slide 3 of 6
The Systems View of Operation Management Figure 1.3 Planning Organizing Inputs Conversion Process Outputs Customers Feedback Controlling

22 Operations Perspective on Quality Slide 4 of 6
Operations/Marketing Interface In recent years, a major advance in operations management has been the improved understanding of the operations/marketing interface. The interface has resulted in an increased focus on the customer. This externalized view is important as operations managers in firms still tend to be focused heavily on meeting production schedules, sometimes at the expense of good quality.

23 Operations Perspective on Quality Slide 5 of 6
Strategic View of Operations Management Among the recent advances in operations management has been a migration towards a more strategic view. Ferdows and Demeyer linked this strategic view of operations management to quality management by proposing the Sand Cone Model in which quality was identified as the base on which lasting improvement in other competitive dimensions were established.

24 Operations Perspective on Quality Slide 6 of 6

25 Strategic Management Perspective on Quality Slide 1 of 3
Nature of the Strategic Management Perspective Strategy refers to the planning processes used by an organization to achieve a set of long term goals. The planned course of action must be cohesive and coherent in terms of goals, policies, plans, and sequencing to achieve quality improvement. Initially, quality-related strategic planning was treated as if it were a separate exercise from firm-level strategic planning. However, quality management, to become pervasive in a firm, needed to be included in all of the firm’s business practices, including strategic planning.

27 Strategic Management Perspective on Quality Slide 3 of 3
Goal of Strategic Quality Planning The ultimate goal of strategic quality planning is to aid an organization to achieve sustainable competitive advantage. Research shows that quality is still the major concern of CEOs.

28 Marketing Perspective on Quality Slide 1 of 3
Nature of Marketing Perspective Marketing efforts are often focused on managing perceptions of quality. Relationship Management Directing attention toward satisfying and delivering value to the customer. Tools for Influencing Customer Perceptions of Quality Price and advertising are the primary tools for influencing customer perceptions of quality, but are imperfect mechanisms.

30 Marketing Perspective on Quality Slide 3 of 3
Focus on Service Another important contribution of the marketing perspective has been the focus on service. Customer service surveys are important tools for assessing the multiple dimensions of quality.

31 Financial Perspective on Quality Slide 1 of 4
Nature of the Financial Perspective One of the most commonly asked questions about quality management is “will it pay us financial benefits?” The financial perspective relies more on quantified, measurable, results-oriented thinking. W. Edwards Deming made the first theoretical attempt to link quality improvements to financial results through the “Deming Value Chain.”

32 Financial Perspective on Quality Slide 2 of 4
The Deming Value Chain Figure 1.8 Improve Quality Cost decrease because of less rework, fewer mistakes, fewer delays, snags; better use of machine-time and materials Productivity Improves Capture the Market Stay in Business Provide Jobs and More Jobs

33 Financial Perspective on Quality Slide 3 of 4
Law of Diminishing Marginal Returns According to this law, there is a point at which investments in quality improvement will become uneconomical. According to the quadratic economic quality level model, higher levels of quality will result in higher expenditures. This view is at odds with the ethic of continual improvement.

34 Financial Perspective on Quality Slide 4 of 4
Basic Economic Quality Level Model Figure 1.9 Cost Total Quality Costs = Sum of Losses and Gains Costs of Improving Quality Minimum Cost Losses due to poor quality Optimum Quality Level Quality

35 Human Resources Perspective on Quality Slide 1 of 3
Nature of Human Resources Perspective Understanding the human resources perspective on quality is essential as it is impossible to implement quality without the commitment and action of employees. Related Concepts Employee Empowerment Organizational Design Job Analysis 360-degree evaluation Total Quality Human Resources Management

36 Human Resource Perspective on Quality Slide 2 of 3
Employee Empowerment Empowering employees involves moving decision making to the lowest level in the organization. Organizational Design Human resources managers are involved in many aspects of organizational design, such as the design of reward systems, pay systems, organizational structure, compensation, training mechanisms, and employee grievance arbitration. Job Analysis Involves collecting detailed information about a particular job.

37 Human Resource Perspective on Quality Slide 3 of 3
360-Degree Evaluation A performance measurement system in which an employee’s peers, supervisors, and subordinates are involved in evaluating the worker’s performance. Total Quality Human Resources Management (TQHRM) TQHRM involves many of the concepts of quality management to provide a more supportive and empowered environment.

38 The Three Spheres of Quality Slide 1 of 4
Figure 1.10 Quality Management Quality Assurance Quality Control

39 The Three Spheres of Quality Slide 2 of 4
Quality Control Includes phases of analysis, relation, and generalization. Activities relating to quality control include: Monitoring process capability and stability Measuring process performance Reducing process variability Optimizing processes to nominal measures Performing acceptance sampling Developing and maintaining control charts

40 The Three Spheres of Quality Slide 3 of 4
Quality Assurance Refers to activities associated with guaranteeing the quality of a product or service. Quality assurance activities include tasks such as: Failure mode and effects analysis Concurrent engineering Experimental design Process improvements Design team formation and management Off-line experimentation Reliability/durability product testing

41 The Three Spheres of Quality Slide 4 of 4
Quality Management The management processes that overarch and tie together the control and assurance activities. Quality management activities: Planning for quality improvement. Creating a quality organizational culture. Providing leadership and support. Providing training and retraining. Designing an organizational system that reinforces quality ideals. Providing employee recognition. Facilitating organizational communication.

42 Other Perspectives on Quality Slide 1 of 2
The Value-Added Perspective on Quality A customer-based perspective on quality that is utilized by services, manufacturing, and public sector organizations. Involves a subjective assessment of the efficacy of every step of the process for the customer.

43 Other Perspectives on Quality Slide 2 of 2
Cultural Perspectives on Quality International marketers have long noted that there are differences in tastes and preferences between cultures and nations. It is not so obvious that approaches to quality improvement may differ according to culture.

44 Contingency Approach to Quality
Contingency Theory Contingency theory presupposes that there is no theory or method for operating a business that can be applied in all situations. As a result, a coherent quality strategy will need to address key environmental variables. Contingency Approach Definitions and dimensions of quality applied within an organization will, and should vary. Dimensions of quality will depend on the environment in which a company operates. Provides flexibility to managers in pursuing quality.

48 What is Theory? Slide 1 of 6 Theory Defined Illustration of a Theory
Theory is a “coherent group of general propositions used as principles of explanation for a class of phenomena.” Illustration of a Theory For example, it might have been observed that many companies that have implemented quality improvements have experienced improved worker morale.

50 What is Theory? Slide 3 of 6 Four Elements of a Theory What How Why
The what of a theory involves which variables or factors are included in the model. How The how of a theoretical model involves the nature, direction, and extent of the relationship between the variables. Why The why or the theory is the theoretical glue that holds the model together. Who-Where-When The who-where-when aspect place contextual bounds on the theory.

54 A Theory of Quality Management? Slide 1 of 2
No Unified Theory As yet, there is not a unified theory explaining quality improvement that is widely accepted by the quality community Differing Approaches The differing approaches to quality improvement represent competing philosophies that have sought their places in the marketplace of ideas.

55 A Theory of Quality Management? Slide 2 of 2
Managers Must Apply What Fits As a result of the availability of competing philosophies of quality management, practicing quality managers must become familiar with these philosophies and apply those that are applicable to their particular situation. The Most Successful Companies The most successful companies have put their own stamp on quality campaigns, mounting their own massive training efforts internally.

W. Edwards Deming Joseph M. Juran Kaoru Ishikawa Armand Feigenbaum Philip Crosby Genichi Taguchi The Rest of the Pack Robert C. Camp Tom Peters Michael Hammer and James Champy

57 W. Edwards Deming Slide 1 of 12
Preeminent Authority W. Edwards Deming was widely accepted as the world’s preeminent authority on quality management prior to his death on December 24, 1993. Deming gained credibility because of his influence on Japanese and American industry. Contributions Fourteen Points for Management The Seven Deadly Diseases Emphasized “continual neverending improvement.”

58 W. Edwards Deming Slide 2 of 12
Deming’s 14 Points for Management While Deming espoused the belief that theory was important to the understanding of quality improvement, the closest he ever came to expounding a theory was in his 14 points for management. Taken as a whole, the 14 points represent many of the key principles that provide the basis for quality management in many organizations.

59 W. Edwards Deming Slide 3 of 12
Deming’s 14 Points for Management 1. Create constancy of purpose. 2. Adopt a new philosophy. 3. Cease mass inspection. 4. End awarding business on the basis of price tag. 5. Constantly improve the system. 6. Institute training on the job. 7. Improve leadership. 8. Drive out fear. 9. Break down barriers between departments. 10. Eliminate slogans. 11. Eliminate work standards. 12. Remove barriers to pride. 13. Institute education and self-improvement. 14. Put everybody to work.

60 W. Edwards Deming Slide 4 of 12
Point 1 Point 2 Create constancy of purpose toward improvement of product and service with the aim to become competitive and stay in business, and to provide jobs. Adopt a new philosophy. We are in a new economic age. Western management must awaken to the challenge, must learn its responsibilities, and take on leadership of change.

61 W. Edwards Deming Slide 5 of 12
Point 3 Point 4 Cease dependence on mass inspection to improve quality. Eliminate the need for inspection on a mass basis by building quality into the product in the first place. End the practice of awarding business on the basis of price tag alone. Instead, minimize total cost. Move toward a single supplier for any one item, based on a long-term relationship of loyalty and trust.

62 W. Edwards Deming Slide 6 of 12
Point 5 Point 6 Institute training on the job. People must have the necessary training and knowledge to do their job. Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease cost.

63 W. Edwards Deming Slide 7 of 12
Point 7 Drive out fear, so everyone may work effectively for the company. Point 8 Improve leadership. The aim of supervision should be to help people, machines, and gadgets to do a better job. Supervision of management is in need of overhaul as well as supervision of production workers.

64 W. Edwards Deming Slide 8 of 12
Point 9 Point 10 Break down barriers between departments. People in research, design, sales, and production must work as a team to foresee problems of production and use that may be encountered with the product or service. Eliminate slogans, exhortations, and targets for the workforce asking for zero defects and new levels of productivity. Such exportations only create adversarial relationships, as the bulk of the causes of low quality and low productivity belong to the system and thus lie beyond the power of the workforce.

65 W. Edwards Deming Slide 9 of 12
Point 11 Point 12 Eliminate work standards on the factory floor. Eliminate management by objectives. Eliminate management by numbers and numeric goals. Substitute leadership. Remove barriers to rob workers of their right to pride in the quality of their work. The responsibility of supervisors must be changed from sheer numbers to quality.

66 W. Edwards Deming Slide 10 of 12
Point 13 Point 14 Put everybody in the company to work to accomplish the transformation. The transformation is everybody’s job. Institute a vigorous program of education and self-improvement. This is a more generalized education than training on the job. Organizational learning requires a structure that reinforces and rewards learning.

67 W. Edwards Deming Slide 11 of 12
Deming’s 7 Deadly Diseases 1. Lack of constancy of purpose. 2. Emphasis on short-term profits. 3. Evaluation of performance, merit rating, or annual review. 4. Mobility of management. 5. Running a company on visible figures alone. 6. Excessive medical costs for employee health care. 7. Excessive costs of warrantees.

68 Joseph M. Juran Slide 1 of 5 Juran’s Approach Key Contributions
Juran tends to take a more strategic and planning-based approach to improvement than does Deming. Juran promotes the view that organizational quality problems are largely the result of insufficient and ineffective planning for quality. Key Contributions Juran Trilogy Control versus Breakthrough Project-by-Project Improvement Pareto Analysis

69 Joseph M. Juran Slide 2 of 5 The Juran Trilogy:
Three basic processes that are essential for managing to improve quality. Planning Improvement Control

70 Joseph M. Juran Slide 3 of 5 Control versus Breakthrough
According to Juran, control is a process-related activity that ensures processes are stable and provides a relatively consistent outcome. Control involves gathering data about a process to ensure that the process is consistent. Breakthrough improvement implies that the process has been studied and some major improvement has resulted in large, nonrandom improvement to the process. It is important to understand that control and breakthrough-related activities should occur simultaneously.

71 Joseph M. Juran Slide 4 of 5 Project-by-Project Improvement
Juran teaches that improvement in organizations is accomplished on a project-by-project basis “and in no other way.” The project-to-project approach advocated by Juran is a planning-based approach to quality improvement. Managers must prioritize which project will be undertaken first based on financial return. This means that analysts must use the language of management, that is, money, in order to help determine which projects should be undertaken.

72 Joseph M. Juran Slide 5 of 5 Pareto Analysis
Joseph Juran identified an economic concept that he applied to quality problems. The economic concept is called Pareto’s law or the 80/20 rule. Using Pareto’s law, we see that the majority of quality problems are caused by relatively few causes.

73 Kaoru Ishikawa Slide 1 of 2
Ishikawa’s Primary Contributions Perhaps Ishikawa’s greatest achievement was the development and dissemination of the basic seven tools of quality (B7). As the developer of these tools, Ishikawa is credited with democratizing statistics. Ishikawa felt that to be successful, firms must make everyone responsible for statistical analysis and interpretation.

74 Kaoru Ishikawa Slide 2 of 2
Ishikawa’s Quality Philosophy Ishikawa spent his life working to improve quality in Japan. His ideas were synthesized into 11 points that made up his quality philosophy. Ishikawa is often overlooked in the U.S.; however, every firm that pursues quality improvement will use his tools.

75 Armand Feigenbaum Slide 1 of 3
Feigenbaum’s primary contribution to quality thinking in America was his assertion that the entire organization should be involved in improving quality. He was the first in the U.S. to move quality from the offices of the specialists back to operating workers. This occurred in the 1950s. Contributions Three-step process to improving quality. Four deadly sins that impede quality improvement. Nineteen steps for improving quality.

76 Armand Feigenbaum Slide 2 of 3
Feigenbaum proposes a three-step process to improving quality. Quality Improvement Quality Technology Organizational Commitment Motivated by leadership Includes statistics and machinery that can improve quality Includes everyone in the quality struggle

77 Armand Feigenbaum Slide 3 of 3
Four Deadly Sins (Major Impediments to Improving Quality) Hothouse quality refers to those quality programs that receive a lot of hoopla and no follow-through. Wishful thinking occurs with those who would pursue protectionism to keep American firms from having to compete on quality. Producing overseas is a panacea sometimes undertaken by managers who wish that out of sight, out of mind could solve quality related problems. Confining quality to the factory means that quality has historically just been viewed as a shop floor concern.

78 Philip Crosby Crosby became very well known for his authorship of the book Quality is Free. The primary thesis of this book was that quality, as a managed process, can be a source of profit for an organization. Crosby specifies a quality improvement program consisting of fourteen steps. These steps underlie the Crosby zero defects approach to quality improvement. His approach emphasizes the behavioral and motivational aspects of quality improvement rather than statistical approaches.

79 Genichi Taguchi Slide 1 of 3
The Taguchi method was first introduced by Dr. Genichi Taguchi to AT&T Bell Labs in 1980. Due to its increased acceptance and utilization, the Taguchi method for improving quality is now commonly viewed to be comparable in importance to the Deming approach, and the Ishikawa concept of total quality management. Unique Aspects of the Taguchi Method Definition of quality Quality loss function Robust design

80 Genichi Taguchi Slide 2 of 3
The Taguchi Method Provides 1. A basis for determining the functional relationship between controllable product or service design factors and the outcomes of a process. 2. A method for adjusting the mean of a process by optimizing controllable variables. 3. A procedure for examining the relationship between random noise in the process and product or service variability.

81 Genichi Taguchi Slide 3 of 3
Definition of Quality In Taguchi’s terms, “ideal quality” refers to a reference point for determining the quality level of a product or service. Quality Loss Function Normally, when specifications are set, a target is specified with some allowance for variation. Taguchi states that any deviation from target specs results in loss to society produced. Robust Design Products and services should be designed so that they are inherently defect free and of high quality.

82 The Rest of the Pack Slide 1 of 3
Robert C. Camp The principle pioneer of benchmarking. Benchmarking is the sharing of information between companies so that both can improve.

83 The Rest of the Pack Slide 2 of 3
Tom Peters Tom Peters is a noted author, consultant, and speaker who is widely recognized. Peters co-authored the book In Search Of Excellence. The research for the book involved a case study of several firms and resulted in eight basic practices found in excellent firms. The eight practices identified with excellent firms include a bias for action, getting close to the customer, promoting entrepreneurship, productivity through people, value-driven management, sticking to the core competencies, lean staff, and implementing appropriate amounts of supervision and empowerment.

84 Resolving the Differences in Quality Approaches, An Integrative View
There are many differences between the approaches to quality management espoused by the experts mentioned in this chapter. However, rather than focusing on differences, it is instructional to review the literature to identify common themes and messages.

85 A Categorization of Quality Management Content Variables
Outer Ring Environmental characteristics Quality breakthrough Figure 2.7 Inner Ring Data gathering Strategic planning Core Leadership Employee improvement Quality assurance Customer role Philosophy Quality department focus Team Approach

86 Quality Management Content Variables Slide 1 of 5
Core Variables Leadership Employee Improvement Quality Assurance Customer Focus Quality Philosophy Breakthrough Inner and Outer Ring Variables Information Analysis Strategic Planning Environment or Infrastructure Team Approach Focus of the Quality Department

87 Quality Management Content Variables Slide 2 of 5
Leadership The role of the leader in being the champion and major force behind quality improvement is critical. Employee Improvement Once the leader is enlightened and motivated to go forward in the quality effort, employees must be trained and developed. Quality Assurance Quality experts agree that quality can be assured only during the design phase. Therefore, effort must be invested in designing products, services, and processes so that they are consistently of high quality.

88 Quality Management Content Variables Slide 3 of 5
Customer Focus An understanding of the customer is key to quality management efforts. Quality Philosophy Adoption of a philosophy toward quality improvement is also important. Establishing a clear message provides a company with a map to follow during their quest for improvement.

89 Quality Management Content Variables Slide 4 of 5
Information Analysis Fact-based improvement refers to an approach that favors information gathering and analysis Strategic Planning This provides a framework for a rational quality strategy that will provide alignment with key business factors. Environment or Infrastructure Quality environment or infrastructure must be created that supports quality management efforts. Team Approach One of the contemporary approaches to quality management learned from the Japanese is teamwork.

90 Quality Management Content Variables Slide 5 of 5
Role of the Quality Department As a result of the dispersion of responsibility for quality, the role of the quality department has changed significantly. Rather than performing the policing function, these departments are filling more of a coaching role. Breakthrough The need to make large improvements is not precluded by continuous improvement. Firms must find ways to achieve radical improvements.

91 Theoretical Framework for Quality Management
Quality management begins with leadership. The quality philosophy influences decision making concerning quality strategy, quality assurance, and employee improvement. The customer is the focus of all activities of the firm. Major activities forming the quality system Breakthrough improvement Team building Data gathering Strategic planning Quality department coaching

Mechanisms That Firms Use In Globalizing Licensing By licensing, a U.S. corporation can allow foreign firms to sell in restricted markets while using the design of the original designer. Partnering Firms also seek international markets through joint ventures or partnering. Globalization Globalization means that a firm fundamentally changes the nature of its business by establishing production and marketing facilities in foreign countries. We refer to these firms as multinational corporations.

100 Malcolm Baldrige National Quality Award Slide 1 of 11
The award is open to small (less than 500 employees) and large firms (more than 500 employees) in the manufacturing and service sectors. It is not open to public-sector and not-for-profit organizations. There can be only two winners per category each year, which limits the number of yearly awards to six. Additional information on the Baldrige award

101 Malcolm Baldrige National Quality Award Slide 2 of 11
Key Characteristics of the MBNQA The criteria focus on business results. Companies must show outstanding results in a variety of areas to win. The Baldrige criteria are nonprescriptive and adaptive. Although the focus on the Baldrige is on results, the means for obtaining these results are not prescribed. The criteria support company-wide alignment of goals and processes. The criteria permit goal-based diagnosis. The criteria and scoring guidelines provide assessment dimensions.

MBNQA Categories Category 1 Award criteria for leadership. The extent to which top management is involved in creating and reinforcing goals, values, directions, customer involvement and other issues. Category 2 Focuses on how the company establishes strategic directions and how it sets it tactical actions plans to implement the strategic plans. Concerned with methods, measures, deployment, and evaluation.

104 Malcolm Baldrige National Quality Award Slide 5 of 11
MBNQA Categories Category 3 Addresses the customer and market focus. The processes for listening to and learning from customers and markets must be evaluated, improved, and kept current. Category 4 Information and analysis relates to the firm’s selection, management, and use of information to support company processes and to improve firm performance.

105 Malcolm Baldrige National Quality Award Slide 6 of 11
MBNQA Categories Category 5 Deals with human resources focus. The workforce is to be enabled to develop and use its full potential, aligned with company objectives. Category 6 Examines the key aspects of process management. This includes customer-focus in design, delivery process design for services and products, support processes, and processes relating to partners.

106 Malcolm Baldrige National Quality Award Slide 7 of 11
MBNQA Categories Category 7 Documents the results of the other six categories and requires a series of tables and graphs that demonstrate the operational and business results of the firm.

107 Malcolm Baldrige National Quality Award Slide 8 of 11
The Baldrige Process The first step is eligibility determination. The completed application is sent to the National Institute of Standards and Technology (NIST). The application is reviewed by examiners and then by judges, who will determine whether the application will be given a consensus score by the examiners. Firms that are granted Baldrige site visits sometimes refer to themselves as “Baldrige Qualified.” The site visit consists of a team of 4 to 6 examiners visiting a company over a period not to exceed one week. One of the most important outcomes is examiner feedback.

111 Quality Improvement: The Japanese Way
Deming Prize Awarded to individuals and groups who have contributed to the field of quality control. Other Japanese Contributions to Quality Thought Juran stated that the genius of the Japanese was in their ability to maintain a focus on the minutia and detail associated with process improvement. There are several uniquely Japanese contributions that are a part of the Japanese approach to production and service.

112 Deming Prize for Quality Slide 1 of 7
The Deming Prize for quality was established in 1951 by the Japanese Union of Scientists and Engineers (JUSE). Three categories of awards Deming Application Prize for Division Deming Application Prize for Small Business Quality Control Award for Factory There is no limit on the number of companies that can receive the award in a given year. The Deming Prize is much more focused on processes than is the Baldrige.

114 Deming Prize for Quality Slide 3 of 7
Deming Categories Policy Org. and Operations The first category of the Deming Prize addresses the areas of management of quality policy, quality formation, policy correctness and consistency, and related topics. The organization and operations portion of the Deming application requires the applicant to document processes for clarifying authority and responsibility, and related topics.

115 Deming Prize for Quality Slide 4 of 7
Deming Categories Information Analysis The information that is collected for this item includes information that is gathered on the outside and inside. The analysis category of the Deming Prize covers the areas of selection of priority problems and themes, correct use of analytical methods, and use of statistical methods.

116 Deming Prize for Quality Slide 5 of 7
Deming Categories Planning for the Future Education & Training To plan well for the future, firms must understand their present condition well, which is the documentation required for this category. Applicants document plans and accomplishments relating to education and training.

117 Deming Prize for Quality Slide 6 of 7
Deming Categories Quality Assurance Quality Effects As discussed in Chapter 1, quality assurance has to do with the design of products and the new product development process. Quality effects relate to the documentation of benefits, outcomes, and results of quality improvement.

118 Deming Prize for Quality Slide 7 of 7
Deming Categories Standardization Control The systems of setting standards, monitoring performance against the standards, and revision of standards are documented. The applicants describe how they are using SQC, control points, control items, statistical thinking, and the current state of control in the company.

119 Other Japanese Contributions to Quality Slide 1 of 7
Lean Production Japanese Total Quality Control (TQC) Visibility In-Process Inspection N = 2 Technique Total Involvement of the Workforce The Five Ss

120 Other Japanese Contributions to Quality Slide 2 of 7
Lean Production Two views emerge in the literature that pertain to Lean (a.k.a. just-in-time (JIT) manufacturing). The first view of Lean is a philosophical view of waste reduction. This view asserts that anything in the process that does not add value for the customer should be eliminated. The second view of Lean is a systems view stating the JIT is a group of techniques or systems focused on optimizing quality processes.

121 Other Japanese Contributions to Quality Slide 3 of 7
Japanese Total Quality Control Just as the Japanese Lean approach requires attention to detail in every aspect of the process, so does the TQC approach. This attention to detail runs deep in the Japanese culture.

122 Other Japanese Contributions to Quality Slide 4 of 7
Visibility Problems must be made visible before they can be addressed. Andon or warning lights Line-stop authority In-Process Inspection All work is inspected at each stage of the process. Workers inspect their own work.

123 Other Japanese Contributions to Quality Slide 5 of 7
N = 2 Technique The N = 2 technique is an alternative to acceptance sampling. Usually, an acceptance sampling plan involves rules such as: If 2 or fewer defects, accept the lot. If more than 2 defects, reject the lot. Total Involvement of Workforce Horizontal deployment means that all departments are involved in quality. Vertical deployment means that all levels of management and workers are actively involved in quality.

124 Other Japanese Contributions to Quality Slide 6 of 7
The Five S’s. The five Ss are a sequential process that companies follow to literally “clean up their acts.” The Ss are: Seri: organizing by getting rid of the unnecessary. Seiton: neatness that is achieved by straightening offices and work areas. Seiso: cleaning plant and equipment to eliminate dirtiness that can hide or obscure problems. Seiketsu: standardizing locations for tools, files, equipment, and all other materials. Shetsuke: discipline in maintain the prior four Ss.

125 Other Japanese Contributions to Quality Slide 7 of 7
Quality Circles Are natural work teams made up of workers that are empowered to improve processes they use. Preventive Maintenance (PM) The idea behind this concept is that the worst condition a machine should ever by is on the day you purchase it.

126 Quality Improvement: The European Way
ISO 9000:2000 Is the European standard for quality that has been expanded worldwide. European Quality Award (EQA) The highest level is the EQA for the most accomplished applicant in a given year. The second level given is the European Quality Prize for other firms that meet the award criteria.

145 Chapter Overview Strategy Content
The Importance of Time in Quality Improvement Leadership for Quality Quality and Ethics Quality as a Strategy Quality Strategy Process Deploying Quality (Hoshin Kanri) Does Quality Lead to Better Business Results?

146 Strategy Content Importance of Quality Planning
Quality improvement is a planned managerial activity. Quality improvement involves identifying potential improvements, prioritizing potential areas for improvement, and planning the implementation of projects and improvements. Strategy Content Variables Among the strategy content variables we discuss are time, leadership, quality costs, generic strategies, order winners, and quality as a core competency. These outline key considerations when developing a strategic plan.

147 Strategy Content Variables
Time Leadership Ethics Quality costs Generic strategies Order winners Quality as a core competency

148 The Importance of Time in Quality Improvement
Two Aspects of Time The time it takes to achieve business goals as a result of quality. The speed at which companies improve. Studies indicate a significant time lag between the implementation of quality improvement programs and recognizable results. Management that is looking for a quick fix to long-term problems probably will not be too satisfied with this fact.

149 Leadership For Quality Slide 1 of 7
The process by which a leader influences a group to move toward the attainment of superordinate goals. A key strategic variable for quality management. Superordinate goals Those goals that pertain to achieving a higher end that benefits not just the individual, but the group.

152 Leadership For Quality Slide 3 of 7
Types of Power Power of Expertise Reward Power If a leader has rewards that he or she can bestow on subordinates in return for some desirable position, the leader has reward power. Sometimes a leader has special knowledge (or is perceived to have special knowledge).

153 Leadership For Quality Slide 4 of 7
Types of Power Coercive Power Referent Power If a leader is charismatic or charming and is followed because he or she is liked, then the leader has referent power. If the leader has power to punish the follower for not following rules or guidelines, the leader has coercive power.

154 Leadership For Quality Slide 5 of 7
Types of Power Legitimate Power Legitimate power comes with the position.

155 Leadership For Quality Slide 6 of 7
Leadership Dimensions Trait dimension Leadership characteristics tied to the personal “traits” of leaders (such as height and intelligence). Leader skills Attributes such as knowledge, communication, planning, and vision. Leader behavior This approach discusses how leaders behave to identify specific leadership styles and the effects of leadership style on subordinate performance.

156 Leadership For Quality Slide 7 of 7
Commitment to Quality An important attribute of quality managers is commitment over the long term. Quality management is hard, painstaking, slow work. Often, victories in quality are rare and should be celebrated - especially at first. Leaders need to provide funding, slack time, and resources for quality improvement efforts to be successful. This commitment is measured in decades, not quarters or budget cycles.

157 Quality and Ethics Quality appears to be good business.
Quality is also good ethics. It is unethical to ship defective products knowingly to a customer. Reliable products reflect an ethical approach to management. There is a need for integrity, which gets down to honesty, in doing business.

158 Quality as Strategy Slide 1 of 8
Quality as a Strategy We now discuss quality as a strategy from the perspective of generic strategies. These generic strategies are cost, differentiation, and focus Costs of Quality There are two broad categories of costs Costs due to poor quality. Costs associated with improving quality.

159 Quality as Strategy Slide 2 of 8
PAF Paradigm Prevention costs are those costs associated with preventing defects and imperfections from occurring. Appraisal costs are associated with the direct costs of measuring quality. Failure costs are roughly categorized into two areas of costs. Internal failure costs are those associated with on-line failure. External failure costs are associated with product failure after the production process.

160 Quality as Strategy Slide 3 of 8
Examples of Appraisal Costs Laboratory acceptance testing Inspection and tests by inspectors Inspection and tests by noninspectors Set-up for inspection and testing Product quality audits Review of test and inspection data On-site performance tests ISO 9000 qualification activates Quality award assessments

161 Quality as Strategy Slide 4 of 8
Examples of Failure Costs Cost of troubleshooting Reinspection of stocks after defect detection Disruption of production schedules Complaint-handling and replacements Cost of corrective maintenance to plant Cost of corrective action to product Lost production Process waste Cost of product scrapped at product audit Cost associated with disposition of scrap

163 Quality as Strategy Slide 6 of 8
Differentiation Through Quality Differentiation is achieved by a competitor if the customer perceives the product or service to be unique in an important way. It is increasingly difficult to differentiate products based on quality alone. Quality Through Focus Think of a product that is particularly regional or is marked to a particular group. That limited region or group is the object of the focus strategy.

164 Quality as Strategy Slide 7 of 8
Order Winners Terry Hill of the London Business School defined a process for setting strategy that is centered on the identification of the order winning criteria (OWC). The organization determines its competitive priorities and defines how it wins orders in the marketplace. The key is reaching a consensus on the OWC by developing an understanding of the markets the company is serving.

165 Quality as Strategy Slide 8 of 8
Quality as Core Competency Quality, in and of itself, is probably not a core competency. The ability to change can be more important than the actual changing technology of the moment for organizations operating in rapidly evolving markets or industries. However, core competency is built on the foundation of a long-term commitment to quality and continual process improvement.

166 Quality Strategy Process Slide 1 of 4
Forced-Choice Model One of several strategic-planning models that could be adapted to demonstrate integrated quality planning. Particularly useful for companies that are relatively inexperienced in strategic planning. Mature Strategic Planning Process A comprehensive strategy development process used in companies with mature quality processes. The process contains quality concerns at every step. Many metrics and indicators are used to monitor performance as it relates to the strategic business plan.

167 Quality Strategy Process Slide 2 of 4
Forced-Choice Model The process begins by sequestering members of upper management at a retreat. An organizational assessment is performed to identify strengths and weaknesses within the firm. An environmental assessment is performed to evaluate the company’s relative position in the marketplace. In the wrap-up session, alternative strategies are developed.

170 Deploying Quality (Hoshin Kanri) Slide 1 of 2
Hoshin is Japanese for a compass, a course, a policy, or a plan. Kanri refers to management control. In English, this is generally referred to as policy deployment. Hoshin Process The company develops a 3 to 5 year plan, and senior executives develop the current year’s Hoshin objectives. Then the process of catchball occurs. This involves reporting from teams and feedback from management. Development of the Hoshin plan results in the cascading of action plans designed to achieve corporate goals.

172 Does Quality Lead to Better Business Results? Slide 1 of 4
The effects of quality on business results is mixed for two primary reasons: First, there are many variables that affect profitability besides quality. Second, many companies implement quality incorrectly. As a result of the mixed results, it is important to understand the relationships between quality and other variables.

173 Does Quality Lead to Better Business Results? Slide 2 of 4
Variables that interrelate with quality Quality and price Quality and cost Quality and productivity Quality and profitability Quality and the environment

174 Does Quality Lead to Better Business Results? Slide 3 of 4
Quality and Price This relationship has long been studied. The price-quality relationship becomes increasingly unclear when culture differences in an international setting are considered. Quality and Cost A fundamental difference exists between a low-price strategy based on competitive pricing, and a low-cost orientation that is based on continual learning and production competence. Quality will tend to provide a competitive advantage.

175 Does Quality Lead to Better Business Results? Slide 4 of 4
Quality and Productivity The relationship between quality and productivity is clear and has been demonstrated over time. The elimination of waste results in higher productivity. Quality and Profitability High quality is no guarantee of success. Firms must still successfully market, manage cash, and do the many other things that ensure profitability. Quality and the Environment Companies have to address environmental issues in ways that involve a focus on prevention.

180 Customer Facts Customers will tell twice as many people about bad experiences as good experiences. A dissatisfied customer will tell 8 to 10 people about bad experiences. Seventy percent of upset customers will remain your customer if you resolve the complaint satisfactorily. It’s easier to get customers to repeat than it is to find new business. Service firms rely on repeat customers for 85% to 95% of their business. Eighty percent of new product and service ideas come from customer ideas. The cost of keeping an existing customer is one-sixth of the cost of attracting a new customer.

181 Customer Defined A customer is the receiver of goods or services.
Typically, this involves an economic transaction in which something of value has changed hands. Internal customers Employees receiving goods or services from within the same firm. External customers Bill-paying receivers of work. The ultimate people we are trying to satisfy. End user Another term that describes customers.

182 Customer-Driven Quality Slide 1 of 3
Customer-Driven Approach Customer driven quality represents a proactive approach to satisfying customer needs that is based on gathering data about our customers to learn their needs and preferences and then providing products and services that satisfy the customer.

183

184 Customer-Driven Quality Slide 2 of 3
The Pitfalls of Reactive Customer-Driven Quality One of the difficulties in satisfying customer requirements is that in a dynamic environment customer needs are constantly changing. Problems occur when customer requirements increase at a faster rate than quality and service improvement. This places the firm in reactive mode and may signal the need for major process and service redesign.

186 What is the Voice of the Customer?
The voice of the customer represents the wants, opinions, perceptions, and desires of the customer. Quality Function Deployment (QFD) “House of quality,” Translates customer wants into a finished product design.

187 Customer-Relationship Management Slide 1 of 8
This view of the customer asserts that he or she is a valued asset to be managed. The tangibles meet the intangibles to provide a satisfying experience for the customer. Four important design aspects Complaint resolution Feedback Guarantees Corrective action or recovery

189 Customer-Relationship Management Slide 3 of 8
Complaint Resolution Complaint resolution is an important part of the quality management system. Three common types of complaints regulatory complaints employee complaints customer complaints. The complaint-resolution process involves the transformation of a negative situation in one in which the complainant is restored to the state existing prior to the occurrence of the problem. Complaint-recovery process

190 Customer-Relationship Management Slide 4 of 8
Complaint Resolution (or recovery) Process Compensate people for losses Apologize to the customer (contrition) Make it easy for the complainant to resolve his or her problem

191 Customer-Relationship Management Slide 5 of 8
Feedback There are two main types of feedback feedback to the customer feedback to the firm as a basis for process improvements Feedback to the firm should occur on a consistent basis with a process to monitor changes resulting from the process improvement. Some customer data is solicited and other data is provided without solicitation.

192 Customer-Relationship Management Slide 6 of 8
Guarantees A guarantee outlines the customer’s rights. The guarantee is both a design and an economic issue that must be addressed by all companies before the first sale occurs. To be effective, a guarantee should be: Unconditional Meaningful Understandable Communicable Painless to invoke

193 Customer-Relationship Management Slide 7 of 8
To be effective, guarantees should be: Unconditional Understandable Meaningful Communicable Painless to invoke

194 Customer-Relationship Management Slide 8 of 8
Corrective Action When a service or product failure occurs, the failure is documented and the problem is resolved in a way that it never happens again. Corporate teams or committees should be in place to regularly review complaints and to improve processes so the problems don’t recur.

195 The Gap Approach to Service Design
Typically, the gap refers to the differences between desired levels of performance and actual levels of performance. The formal means for identifying and correcting these gaps is called gap analysis.

196 The Gap Approach to Service Design
Word of mouth communications Personal needs Past experience Expected service Gap 5 Perceived service Marketer Gap 4 Service delivery External communications to consumers Gap 3 Gap 1 Translation of perceptions into service quality specs Gap 2 Management perceptions of consumer expectations Figure 5.3

198 Segmenting Customers and Markets
Segmenting Data To segment markets means to distinguish customers or markets according to common characteristics. Segmentation implies that data is gathered separately for each segment and analyzed separately.

199 Strategic Alliances Between Customers and Suppliers
Strategic Partnerships Increasingly, sole sourcing arrangements are developing into strategic partnerships where the suppliers become de facto subsidiaries to their major customers. In these arrangements, not only are suppliers sole source providers, but also they integrate information systems and quality systems that allow close interaction at all levels.

200 Communicating With Customers

208 Managing Customer Retention and Loyalty
Customer retention is measured as the percentage of customers that return for more service. Customer retention will increase by application of the service tools and concepts contained in this chapter such as tools for data gathering and analysis. Customer Loyalty Customer loyalty can be instilled by offering specialized service not available from competitors. This can take many forms including high customer contact or technology advancements.

This can be a useful activity; however, companies often have variations in the way they compute their measures that affect the result. Productivity Total factor productivity is the least sensitive to differences in costing conventions and accounting practices.

228 Difficulties in Monitoring and Measuring Performance
Comparative measures Concentrating too much on comparative measures can focus managers on results and not causes. Could result in the development of numerical goals that ignore the necessity of improving the system of production. Comparisons with foreign companies Problems become even more pronounced, because cost accounting conventions and accepted accounting principles can vary greatly between countries.

229 Commonly Benchmarked Performance Measures Slide 1 of 4
Benchmarking Data Financial ratios Productivity ratios Customer-related results Operating results Human resource measures Quality measures Market share data Structural measures

230 Commonly Benchmarked Performance Measures Slide 2 of 4
Financial Ratios Such as ROA or ROI are probably the easiest to obtain and compare. Productivity Ratios Are useful in measuring the extent to which a firm effectively uses the scarce resources that are available to it. Customer-Related Results Include customer satisfaction and comparisons of customer satisfaction relative to competitors.

231 Commonly Benchmarked Performance Measures Slide 3 of 4
Operating Results Might include cycle times, waste reduction measures, value-added measures, and lead time. Human Resource Measures May include employee satisfaction measures, training expenditures, turnover, and absenteeism. Quality Measures These can include conformance-based quality information such as reject rates, capability information, performance information, or other measures.

232 Commonly Benchmarked Performance Measures Slide 4 of 4
Market Share Data Includes shares in the different markets served by the firm. Structural Measures Include objectives, policies, and procedures followed by a firm.

233 Best-In-Class Benchmarking
Best-in-breed Refers to those firms or organizations that have been recognized as the best in an industry based on some criterion. Generally, initiator firms will choose to benchmark the best-in-class. Objective The objective of best-in-class is to provide a basis for continual improvement.

234 Best-Of-The-Best Benchmarking
Best-in-the-world The next level of improvement after becoming a best-in-class firm, because it may be difficult to gain new insight and information from direct competitors. Can lead to breakthrough improvement by causing individuals within firms to look at other industries and to visualized the business in new and different ways.

235 Business Process Benchmarking Slide 1 of 4
Based on the concept of 5w2h developed by Alan Robinson. 5w2h concept A business process benchmarking project should result in answers to seven questions What? Why? Where? When? Who? How? How much?

251 Problems With Benchmarking Slide 1 of 2
There is enormous difficulty obtaining cooperation from other firms in your own industry. The thing to remember is reciprocity. The predominance of functional benchmarking with firms in noncompeting industries makes it difficult to benchmark these firms. Business and industry literature can be very helpful in trying to identify benchmarking firms in noncompetitive industries.

252 Problems With Benchmarking Slide 2 of 2
Your efforts will be wasted unless you fully understand your own processes before you benchmark against someone else. Using tools such as business process maps, it is possible to identify the exact performance measures and metrics needed from the target firm. Benchmarking is time consuming and costly. Costs include things like time for planning, travel, documentation, and implementation. Largest costs are associated with implementation. The investment is lost if benchmarking data are not used to drive improvement.

Quality Function Deployment (QFD) Technology in Design Prototyping Methodologies Designing for Reliability Environmental Considerations in Design

257 Designing Products for Quality
Each dimension of quality poses different design problems. Design is not strictly a technical decision to be made by engineers. Engineers need input from marketing and operations to understand customer needs, marketing requirements, and the realities of production.

258 The Design Process Slide 1 of 4
Project Development Process Figure 7.1

259 The Design Process Slide 2 of 4
Stage 1: Product Idea Generation External and internal sources brainstorm new concepts. Internal sources include marketing, management, R&D, and employee suggestions. The primary source for external product ideas is the customer. Stage 2: Customer Future Needs Projection This stage uses data to predict future customer needs. Stage 3: Technology Selection for Product Development Designers choose the materials and technologies that will provide the best performance for the customer at an acceptable cost.

260 The Design Process Slide 3 of 4
Stage 4: Technology Development For Process Design Designers choose the processes that will be used to transform the materials picked in the prior stage into final products. Stage 5: Final Product Definition Results in final drawings and specifications for the product with product families by identifying base product and derivative products. Stage 6: Product Marketing and Distribution Preparation Includes activities such as the marketing plan.

261 The Design Process Slide 4 of 4
Stage 7: Product Design and Evaluation Requires definition of the product architecture, the design, production, testing of subassemblies, and testing of the system for production. Stage 8: Manufacturing System Design Includes the selection of the process technologies that will result in a low-cost, high-quality product. Stage 9: Product Manufacture, Delivery and Use Finishes the process. The customer then enjoys the result of the design process.

262 Quality Function Deployment (QFD) Slide 1 of 2
Describes a method for translating customer requirements into functional design. Sometimes this process translation is referred to as the voice of the customer. Designers need a means for implementing customer requirements into designs. The house of quality (QFD) is used to accomplish this.

263 Quality Function Deployment (QFD) Slide 2 of 2
QFD Layout: The House of Quality Figure 7.2

264 Steps in QFD Slide 1 of 5 Step 1: Develop a list of customer requirements. Step 2: Develop a listing of technical design elements along the roof of the house. Step 3: Demonstrate the relationship between the customer requirements and technical design elements. Step 4: Identify the correlations between design elements in the roof of the house. Step 5: Perform a competitive assessment of the customer requirements. Step 6: Prioritize customer requirements. Step 7: Prioritize technical requirements. Step 8: Final Evaluation.

265 Steps in QFD Slide 2 of 5 Step 2: Develop a listing of technical design elements along the roof of the house. Step 1: Develop a list of customer requirements The list of customer requirements includes the major customer needs as they relate to a particular aspect of a process. These are the design elements that relate to customer needs.

266 Steps in QFD Slide 3 of 5 Step 3: Demonstrate the relationship between the customer requirements and technical design elements Step 4: Identify the correlations between design elements in the roof of the house The correlations can be identified through the use of symbols. A diagram can be used to demonstrate these relationships.

267 Steps in QFD Slide 4 of 5 Step 5: Perform a competitive assessment of the customer requirements Step 6: Prioritize customer requirements Articulate customer requirement priorities. Compare your product with those of your key competitors.

268 Steps in QFD Slide 5 of 5 Step 7: Prioritize technical requirements
Step 8: Final Evaluation The relative and absolute weights for technical requirements are evaluated to determine what engineering decisions need to be made to improve the design based on customer input. Prioritize the technical requirements that fit your product design.

269 Technology in Design Slide 1 of 3
Computer-Aided Design (CAD) System These systems are used in designing anything from an ultralight airplane, to a hamburger, to a home, or to a new intersection that can handle higher volumes of traffic. Greatly improve the ability of designers to generate new and varied designs. Simplify the design process. Help to develop more reliable and robust systems.

270 Technology in Design Slide 2 of 3
Multiuser CAD Systems An important advance in CAD systems has been the advent of multiuser CAD systems. Using a common database in a network, multiple designers in locations worldwide can work on a design simultaneously, around the clock. Geometric Modeling Is used to develop a computer compatible mathematical description of a part. The image is typically a wire frame drawing of a component.

271 Technology in Design Slide 3 of 3
Engineering Analysis May involve many different engineering tests such as heat-transfer calculations, stress calculations, or differential equations to determine the dynamic behavior of the system being designed. Interference Checking Examining a design to see if different components in a product occupy the same space. Closed-Loop Systems CAD/CAM systems are often tied together in a closed-loop system with computer-aided inspection (CAI) and computer-aided testing (CAT) quality control systems.

272 Prototyping Methodologies Slide 1 of 3
Is an iterative approach to design in which a series of mock products are developed until the customer and the designer agree on the final design.

273 Prototyping Methodologies Slide 2 of 3
Types of Prototypes Basic prototype. The basic prototype is a nonworking mock-up of the product that can be reviewed by customers prior to acceptance. Paper prototypes. Consist of a series of drawings developed by the designer on CAD systems and reviewed by decision makers prior to acceptance. Working prototypes. These are fully working models of the final product.

274 Prototyping Methodologies Slide 3 of 3
Organizing the Design Team Perform design steps sequentially. Perform design steps simultaneously. Concurrent Engineering The simultaneous performance of product design and process design. Typically, concurrent engineering involves the formation of cross-functional teams. This allows engineers and mangers of different disciplines to work together simultaneously in developing product and process designs.

275 Product Life Cycle and Related Topics Slide 1 of 4
The Product Life Cycle (PLC) The product life cycle concept demonstrates the need for developing new products by showing product design, redesign, and complementary product development on a continuum. Product Life Cycle Imperatives First, product life cycles are becoming shorter. Second, as product life cycles shorten, product variety and change become much more important to the successful competitor as complementary products are needed to consume productive capacity

276 Product Life Cycle and Related Topics Slide 2 of 4
Complementary Products Are new products using similar technologies that can coexist in a family of products. Extend the life of a product line by offering new features or improvements to prior versions of a product. Design for Manufacture (DFM) Means to design products so they are cost effective and simple to build. Design for Manufacture Methods Intended to eliminate over-the-wall syndrome and radically reduce design cycle times.

278 Product Life Cycle and Related Topics Slide 3 of 4
Enterprise Resource Planning (ERP) System A system that integrates financial, planning, and control systems into a single architecture. Examples include the SAP R/3 system and Oracle. Product Data Management (PDM) Helps manage both product data and the product development process by tracking the masses of data needed to design, manufacture, support, and maintain products.

279 Product Life Cycle and Related Topics Slide 4 of 4
Design for Maintainability A concept that states that products should be designed in a way that makes them easy for consumers to maintain. Design for Maintainability Concepts Components that are easily replaced. Components that are easily removed with standard tools. Adequate space to perform the maintenance function. Nondestructive disassembly. Safe maintenance. Available adequate owners manuals and documentation.

280 Design for Reliability Slide 1 of 11
Dimension of reliability Failure rate Time Component Reliability Is defined as the propensity for a part to fail over a given time. System Reliability Refers to the probability that a system of components will perform their intended function over a specified period of time.

281 Design for Reliability Slide 2 of 11
Reliability Analysis Tools Failure Modes and Effects Analysis (FMEA) Fault Tree Analysis Failure Modes, Effects, and Criticality Analysis (FMECA)

282 Design for Reliability Slide 3 of 11
Failure Modes and Effects Analysis (FMEA) Method for systematically considering each component of a system, identifying, analyzing, and documenting the possible failure modes within a system and the effect of each failure on the system. Benefits of FMEA Improvement of product safety, quality, and reliability. Improvement of a company’s image and competitiveness. Increased satisfaction from a user standpoint. Reduction in product development cost. Record of action taken to reduce a product risk.

283 Design for Reliability Slide 4 of 11
Basic areas where FMEA can be applied Concept: FMEA is used to analyze a system or its subsystems in the conception of the design. Process: FMEA is applied to analyze the assembly and manufacturing processes. Design: FMEA is used for analysis of products before mass production of the product begins. Service: FMEA is used to test industry processes for failure prior to their release to customers. Equipment: FMEA can be used to analyze equipment before the final purchase.

285 Design for Reliability Slide 6 of 11
Fault Tree Analysis An analytical tool that graphically renders the combinations of faults that lead to the failure of the system. This technique is useful for describing and assessing the events within a system. Primary Symbols of Fault Tree Analysis Events Gates Link the faults to the undesired events within the diagram. Gates show how faults are related.

286 Design for Reliability Slide 7 of 11
Types of Events (in Fault Tree Analysis) Basic events are initiating faults that do not require events below them to show how they occurred. The symbol used for a basic event is a circle. An intermediate event is the result of a combination of faults, some of which may be primary events. This intermediate event is located in the middle of a fault tree. These events are described by rectangles. An expanded event requires a separate fault tree because of its complexity. For this new fault tree, the expanded event is the undesired event and would be located at the top of the fault tree.

287 Design for Reliability Slide 8 of 11
Fault Tree Diagram Figure 7.20

288 Design for Reliability Slide 9 of 11
Steps in Fault Tree Analysis Become familiar with the system. Define the undesired events of the system with the related contributing and initiating events. Develop fault trees for the undesired events. Obtain probabilities for the events on the fault trees. Evaluate fault trees. Analyze the results and proposals for system improvement. Change the fault trees to reflect proposed improvements and renewed fault tree evaluation. Perform a worst case analysis.

289 Design for Reliability Slide 10 of 11
Failure Mode, Effect, and Criticality Analysis (FMECA) An extensive, but simple method for identifying ways in which an engineered system could fail. Criticality In FMECA is important because it prioritizes how the design team should be spending its resources. In general, criticality refers to how often a failure will occur, how easy it is to diagnose, and whether it can be fixed. Critically assessment is somewhat subjective because it depends on the viewpoint of a service or field analysis.

290 Design for Reliability Slide 11 of 11
Product Traceability The ability to trace a component part of a product back to its original manufacturer. Consumer Product Safety Commission (CPSC) An independent federal regulatory agency that helps keep American families safe by reducing the risk of injury or death from consumer products.

291 Environmental Conditions in Design Slide 1 of 2
Importance Currently, society demands much more from product designers than just high-quality products. Many manufacturers have turned to a more environmental form of manufacturing that offers positive returns on investment. Green Manufacturing Movement that began in Germany with requirements for importers to remove packaging materials.

292 Environmental Conditions in Design Slide 2 of 2
Design for Reuse Designing products so they can be used in later generations of products. Design for Disassembly A method for developing products so that they can easily be taken apart. Design for Remanufacture A method for developing products so that they parts can be used in other products. Associated with green manufacturing.

296 Differences Between Services and Manufacturing Slide 1 of 3
Unique Attributes of Services The output of services is heterogeneous Services are intangible The production and consumption of services often occur simultaneously Customers are more involved in the production of services than they are in manufacturing

297 Differences Between Services and Manufacturing Slide 2 of 3
Intangible Many service attributes are intangible. This means that they cannot be inventoried or carried in stock over long periods of time. Heterogeneous This means that for many companies, no two services are exactly the same. Simultaneous Production and Consumption Customer Contact Customers tend to be more involved in the production of services than they are in manufacturing.

298 Differences Between Services and Manufacturing Slide 3 of 3
Internal Versus External Services External services are those whose customers pay the bills. Internal services are in-house services such as data processing, printing, and mail. Voluntary Versus Involuntary Services Voluntary services are those services that we actively seek out and employ of our own accord. The quintessential example of an involuntary service is a prison. Other involuntary services include hospitals, the IRS, and the fire department.

319 Designing & Improving the Services Transaction (Services Blueprinting) Slide 3 of 5
Steps in Developing a Service Blueprint Step 1: Identify processes. Processes are flowcharted so that the bounds of the process are identified. Step 2: Isolate fail points. What can happen here? What could go wrong. Mistakes can be expensive. Step 3: Establish a time frame. Time can be a major determinant of profitability. Those steps that lose time result in lost income. Time standards should be established for each step in the process. Step 4: Analyze profits. As errors occur in the process, the service provider becomes liable. Because delays and errors affect profitability, the provide could lose money.

320 Designing & Improving the Services Transaction Slide 4 of 5
Line of Visibility Identifies the point beyond which activities are not seen by the customer, but still influence performance. Moments of Truth The fail points in the service blueprint are also referred to as moments of truth. These are times at which the customer expects something to happen. Poka-Yoke The idea behind poka-yoke (or fail-safing) is to ensure that certain errors will never occur.

325 Globalization of Services
The trend toward globalization the way we manage service quality. Eastern European and Eastern Asian countries are following the lead of the United States by transferring labor and GDP into the services sector. The implication is that service competition will increase on a global scale, as has been the case in manufacturing for the past 40 years.

326 Improving Customer Service In Government
If customer service is the battlefield for business leading into the twenty-first century, then government is probably the last frontier. There are some evidences of improvement in several aspects of government service.

327 Quality in Health Care Several factors have contributed to increased attention in the area of health care Health care is facing the same “cost squeeze” that government is facing. A move toward HMO’s is causing hospitals to streamline operations. There is increasing diversity in health care. Calls for a nationalized health care system threaten the status quo an provide the competitive pressures that spur the impetus to improve.

329 A Theory For Service Quality Management Slide 2 of 5
Proposition 1: The Unified Services Theory “With services, the customer provides significant inputs into the production process. With manufacturing, groups of customers may contribute ideas to the design of the product; however, individual customers’ only part in the actual process is to select and consume the output. Nearly all other managerial themes unique to services are founded in this distinction.

330 A Theory For Service Quality Management Slide 3 of 5
Proposition 2: The Unreliable Supplier Dilemma “With services, the customer-suppliers often provide unreliable inputs.”

331 A Theory For Service Quality Management Slide 4 of 5
Proposition 3: Capricious Labor “With services, customer-labor may ignore, avoid, or reject technologies or process improvements which are intended to increase quality and productivity. As a result, customer buy-in to process changes must be carefully addressed.”

332 A Theory For Service Quality Management Slide 5 of 5
Proposition 4: Everyone Presumes to be An Expert “With services, the customer often provides product specifications (what to make) and process design (how to make it), often without the invitation of the service provider.”

336 The Value Chain Slide 1 of 4
A tool that disaggregates a firm into its core activities to help reduce costs and identify sources of competitiveness. Value System Consists of a network of value chains.

337 The Value Chain Slide 2 of 4
Figure 9.1 Firm infrastructure Support Activities (Hidden factory) Human resource management Technology development Margin Procurement Inbound logistics Operations Outbound logistics Marketing and sales Service Margin Core Activities

338 The Value Chain Slide 3 of 4
The Chain of Customers Looking at the activities along the value chain sequentially, we see that the links in the value chain are really people performing different functions. The chain of customers is revealed when you view the next step in the chain after you as your own customer. This means that if you work at workstation 4 in a process at the core of the value chain, you will make sure that the work you do is absolutely impeccable before you release it to your “customer” in workstation 5.

339 The Value Chain Slide 4 of 4
Managing the Supply Chain The concept of supply chain management extends the economic concept of value chain. One of the most significant aspects of the value chain is the linkage between a series of suppliers and consumers. This linkage is especially tenuous because it involves the complex interaction of logistics, systems, and human behavior.

342 Supplier Partnering Slide 3 of 5
Supplier Partnering Approaches Single sourcing Refers to narrowing down the list of approved supplier for a single component to just one supplier. Dual Sourcing Companies that are uncomfortable with using a single supplier may use dual sourcing where the number of approved suppliers is reduced to just a few. Supplier Evaluation Is a tool used by many firms to differentiate and discriminate between suppliers. Supplier evaluations are often recorded on report cards in which potential supplier are rated on criteria such as quality, technical capability, or ability to meet schedule demands.

343 Supplier Partnering Slide 4 of 5
Supplier Partnering Approaches Sole-Source Filters That are used in many companies rely on external validation of quality programs. Two of the most common filters are the Baldrige criteria and ISO 9000:2000. Supplier Evaluations Many companies perform lengthy inspections of their suppliers. These programs are often called supplier certification or qualification programs if the focus is entirely on evaluation. Supplier Development If the focus is on helping the supplier improve, then the programs are called supplier development programs.

348 A Supplier Development Program: QS 9000
A supplier development program developed by a Chrysler/Ford/GM supplier requirement task force. The task force was impaneled to develop standard reference manuals, reporting formats, and technical terminology. The goal of QS 9000 is to enhance quality systems for suppliers while eliminating redundant requirements and reducing costs.

351 QS 9000 Requirements Slide 3 of 10
Management Responsibility Supplier management is responsible for defining and documenting its policies for quality along with its objectives and its level of commitment. Quality System The supplier firm is required to establish, document, and maintain a quality system so that the product conforms to requirements. Contract Review The supplier examines the steps associated with contracting with its own suppliers.

352 QS 9000 Requirements Slide 4 of 10
Design Control This standard focuses on designing processes. To meet requirements, suppliers establish and maintain procedures for controlling the design of the product. Document and Data Control Includes the procedures or approvals used in issuing documents and data and making changes to such data. Purchasing To satisfy requirements for purchasing, the supplier must establish and maintain documents of procedures to ensure that purchased products conform to specified standards.

353 QS 9000 Requirements Slide 5 of 10
Control of Customer-Supplied Product The standard for this part of the QS 9000 standard is worded as follows, “Suppliers must establish and maintain documented procedures for the control of verification, storage, and maintenance of customer-supplied product provided for incorporation into supplies or for related activities.” Product Identification and Traceability QS 9000 requires documented procedures for product traceability during all stages of the production process.

354 QS 9000 Requirements Slide 6 of 10
Process Control The element relating to process control establishes that suppliers identify and plan the production, installation, and servicing processes that result in quality products. Inspection and Testing These activities are put in place to ensure that specified requirements for products are met. Control of Inspection, Measuring, and Test Equipment Suppliers must establish and document procedures to control, calibrate, and maintain test equipment.

355 QS 9000 Requirements Slide 7 of 10
Inspection and Test Status The QS 9000 standard requires that inspection test status be maintained throughout the production process, installation process, and service processes of the product. Control of of Nonconforming Product When nonconforming products are produced, they can be reworked to meet specified requirements accepted with or without repair concessions regraded for alternative applications rejected and scrapped.

356 QS 9000 Requirements Slide 8 of 10
Corrective and Preventive Action When problems result in defective products, a standard process for addressing them is needed so that corrective and preventive action can take place in a disciplined way. Handling, Storage, Packaging, Preservation, and Delivery This standard addresses logistics and inventory control. Among the areas to be documented are inventory control methods, such as models, the way inventory turnovers are optimized and how inventory levels are minimized.

357 QS 9000 Requirements Slide 9 of 10
Control of Quality Records The records control standard states that the supplier must establish and follow documented procedures for identifying, collecting, indexing, accessing, filing, storing, maintaining, and disposing of quality-related records. Internal Quality Audits Suppliers are required to perform internal quality audits to ensure compliance with QS 9000 requirements.

358 QS 9000 Requirements Slide 10 of 10
Training A supplier firm must have documented procedures for assessing training needs and for training all personnel who might impact a company’s quality. Servicing This requirement states that servicing efforts should meet the customer’s specified requirements. Statistical Techniques SPC and process capability measures must be maintained. Appropriate statistical techniques are chosen during advanced quality planning and must be maintained in the control plan.

359 Reflecting on QS 9000 QS 9000 is fundamentally different from ISO 9000. QS 9000 is specifically designed to help automakers prove they have standardized processes for dealing with their customers. There is much more guidance given to suppliers in the QS 9000 standard.

360 Acceptance Sampling Slide 1 of 4
Technique used to verify that incoming goods from a supplier adhere to quality standards. Acceptance sampling inspection can range from 100% of the delivery to a relatively few items from which the receiving firm draws inferences about the whole shipment.

361 Acceptance Sampling Slide 2 of 4
Examples of when acceptance sampling might be needed When dealing with new or unproven suppliers. During start-ups and when building new products. When products can be damaged in shipment. When dealing with extremely sensitive products that can be damaged easily. When products can spoil during shipment. When problems with a certain supplier have been noticed in the production process that bring the supplier’s performance into question.

362 Acceptance Sampling Slide 3 of 4
Acceptance Sampling Fundamentals We define acceptance sampling as a statistical quality control technique used in deciding to accept or reject a shipment of input or output. Producer’s and Consumer’s Risk Producer’s risk is the risk associated with rejecting a lot of materials that has good quality. Consumers risk is the risk associated with accepting a lot of materials that has poor quality.

363 Acceptance Sampling Slide 4 of 4

364 Statistical Sampling Techniques Slide 1 of 8
Acceptable Quality Level (AQL) The maximum percentage or proportion of nonconformities in a lot or batch that can be considered satisfactory as a process average. Lot Tolerance Percent Defective (LTPD) The level of poor quality that is included in a lot of goods.

365 Statistical Sampling Techniques Slide 2 of 8
n and c Assignment of AQL, LTPD, alpha and beta is a management decision for the most part. These values define the sampling plan n = the sample size of a particular sampling plan c = the maximum number of defective pieces for a sample to be rejected

366 Statistical Sampling Techniques Slide 3 of 8
OC Curves The operating characteristic (OC) curve provides an assessment of the probabilities of acceptance for a shipment, given the existing quality of the shipment. Constructed to show the probability of accepting individual lots. Higher values of c lead to higher probabilities of accepting bad shipments (consumer’s risk). Higher values of n create a greater confidence that a good shipment has been accepted.

371 Statistical Sampling Techniques Slide 8 of 8
More Complex Sampling Plans Multiple sampling plans have advantages over single sampling plans. Samples sizes will be smaller on average with the same amount of protection. Developing Double Sampling Plans Although OC curves can be used to develop double sampling plans, the calculations to develop the OC curves are much more complex than for single sampling plans. The textbook uses a standard approach that is used by many practitioners. The main limitation of this plan is that sample sizes must be specified, as well as AQL, LTPD, producer’s risk, and consumer’s risk.

375 The Value Chain Slide 1 of 4
A tool that disaggregates a firm into its core activities to help reduce costs and identify sources of competitiveness. Value System Consists of a network of value chains.

376 The Value Chain Slide 2 of 4
Figure 9.1 Firm infrastructure Support Activities (Hidden factory) Human resource management Technology development Margin Procurement Inbound logistics Operations Outbound logistics Marketing and sales Service Margin Core Activities

377 The Value Chain Slide 3 of 4
The Chain of Customers Looking at the activities along the value chain sequentially, we see that the links in the value chain are really people performing different functions. The chain of customers is revealed when you view the next step in the chain after you as your own customer. This means that if you work at workstation 4 in a process at the core of the value chain, you will make sure that the work you do is absolutely impeccable before you release it to your “customer” in workstation 5.

378 The Value Chain Slide 4 of 4
Managing the Supply Chain The concept of supply chain management extends the economic concept of value chain. One of the most significant aspects of the value chain is the linkage between a series of suppliers and consumers. This linkage is especially tenuous because it involves the complex interaction of logistics, systems, and human behavior.

413 Chapter Overview Leading Teams for Quality Improvement Types of Teams
Implementing Teams Managing and Controlling Projects

414 Need for Employee Participation Slide 1 of 3
In their classic article on quality and participation, Robert Cole and his coauthors explained the need for employee participation as a key element in managing changing organizations in an increasingly complex world. W.Edwards Deming, Joseph Juran, Philip Crosby and other influential voices are calling for participation and teamwork to manage businesses today.

415 Need for Employee Participation Slide 2 of 3
Reasons for participation and teamwork Complexity in the workplace Business is shifting away from a “command and control” environment to one of collaboration. Complexity is driving workers to perform more knowledge work, which implies a greater amount of ambiguity, searching, researching, and learning in the job environment . Teamwork is the natural result of collaborative practices being adopted in business. Teams are a fundamental part of projects.

416 Need for Employee Participation Slide 3 of 3

417 Teamwork What is a Team? Focus of the Chapter
A team is defined as a finite number of individuals who are united in a common purpose. Focus of the Chapter Leading teams Managing projects

418 Why Employees Enjoy Teams Slide 1 of 2
Mutuality The need for mutual support and encouragement as well as personal loyalty. Recognition for Personal Achievement The opportunity for personal development as well as recognition for personal achievement through rewards, incentives, or status. Belonging The individual’s need for supportive, cohesive, and friendly team relations. This implies clear communications as well as clear information and project goals.

419 Why Employees Enjoy Teams Slide 2 of 2
Bounded Power The need for authority and control over project resources and people, personal accountability and challenge, individuals’ abilities to influence decision that affect the project, and opportunities for personal growth and development. Creative Autonomy The need for individuals to have the opportunity to use their creativity and potential during the course of a project and to enjoy good working conditions.

420 Leading Teams for Quality Improvement Slide 1 of 12
Employee Empowerment Empowerment means giving power to team members who previously had little control over their jobs. When such power is given, management must follow through and give up a reasonable amount of control.

421 Leading Teams for Quality Improvement Slide 2 of 12
Series of Promises to Employees Implicit in Empowerment Include: You will have greater control over your work. You will not be penalized for making decisions that don’t pan out. Management is committed quality improvement over the long haul. Management will concede more control over company systems to you. Management values your ideas and opinions and will give them serious consideration. Management trusts you and deserves trust in return.

422 Leading Teams for Quality Improvement Slide 3 of 12
Preconditions Necessary for Empowerment Adequate communication and information for decision making Clear authority and accountability Participation in planning at all levels Responsibility with authority

423 Leading Teams for Quality Improvement Slide 4 of 12
Organizational Learning This implies change in organizational behavior in a way that improves performance. This takes place through a network of interrelated components including teamwork, strategies, structures, cultures, systems, and their interactions. Corporate learning relies on an open culture.

424 Leading Teams for Quality Improvement Slide 5 of 12
Flattening Hierarchies for Improved Effectiveness The trend is to eliminate layers of bureaucratic managers in order to improve communication and simplify work. Too many layers of management can also impede creativity, stifle initiative, and make empowerment impossible.

425 Leading Teams for Quality Improvement Slide 6 of 12
Team Leader Role and Responsibility Quality professionals are unanimous – to be successful in achieving teamwork and participation, strong leadership both at the company level and within teams is essential. In most organizations, employees want leaders who provide clear direction, necessary information, feedback on performance, insight, and ideas. Quality management is not a vehicle by which leaders abdicate their responsibility.

426 Leading Teams for Quality Improvement Slide 7 of 12
Situational Leadership Model Theory proposed by Hersey and Blanchard Clarifies the interrelationship between employee preparedness and effectiveness of leadership According to this model, situational leadership is based on interplay among the following: The amount of guidance and direction a leader gives (task behavior). The amount of socioeconomic support a leaders provides (relationship behavior). The readiness level the followers exhibit in performing a specific task, function, or objective.

427 Leading Teams for Quality Improvement Slide 8 of 12
Situational Leadership Model (continued) Readiness is the extent to which a follower has the ability and willingness to accomplish a specific task. Readiness is a function of two variables. Ability and technical skills (job maturity) Self-confidence in one’s abilities (psychological maturity) The situational leadership model has four different styles of leadership which are driven by different contingencies. According to the model, the best approach to leading depends on the readiness of employees to perform tasks and functions or accomplish objectives.

Stages of a Team’s Development Forming The team is composed and the objective for the team is set. Storming Team members begin to get to know each other and agreements have not been made that facilitate smooth interaction. Norming The team becomes a cohesive unit and interdependence, trust, and cooperation develop. Performing A mutually supportive, steady state is achieved. Mourning Team members regret the end of the project and team breaking up.

431 Leading Teams for Quality Improvement Slide 12 of 12
Team Rules Often useful for teams to establish ground rules in order to be functional. Ground rules can forestall conflict. If a team is functional, individual participation enhances the group’s effectiveness. If a team is dysfunctional, individual participation reduces the effectiveness of the group.

432 Types of Teams Slide 1 of 4 Team Type Scope
Process Improvement team Local or single department Cross-function team Multiple departments Tiger team Organization-wide Natural work team Customer- or region-centered Self-directed work team Narrow or broad

433 Types of Teams Slide 2 of 4 Process Improvement Teams
Teams that work to improve processes and customer service. Cross-Functional Teams Teams that enlist people from a variety of functional groups within the firm. Formed to solve problems that cut across functional borders. Tiger Teams A high-powered team assigned to work on a specific problem for a limited amount of time.

434 Types of Teams Slide 3 of 4 Natural Work Group
Teams organized around a common product, customer, or service. Self-Directed Work Teams A team chartered to work on projects identified by team members themselves. Identified as either little s or big S teams. Virtual Teams Teams that rarely or never physically meet, except in electronic meetings using group decision software.

436 Implementing Teams Slide 1 of 3
Facilitation Helping or aiding teams by maintaining a process orientation and focusing the group. Team Building Accomplished by following a process that identifies roles for team members and then helps them to become competent in achieving those roles. Role of the Facilitator Make it easy for the group to know where they are going, know why they want to go there, know how to get there, and know what they’re going to do next.

437 Implementing Teams Slide 2 of 3
Meeting Management Effective meeting management is an important skill for a facilitator of quality improvement teams. Steps required for meeting management: Defining an agenda. Developing meeting objectives. Designing the agenda activity outline. Using process techniques.

438 Implementing Teams Slide 3 of 3
Structured Processes Set of rules for managing meetings Help meetings to stay focused, to involve deeper exploration, to separate creative from evaluative activities, to provide equal opportunity for contribution, to encourage reflection, to provide objective ground rules to reduce defensiveness, and to separate the person from the idea. Parking Lot A flipchart or whiteboard where topics that are off-the-shelf are parked with the agreement that these topics will be candidates for the next meeting’s agenda.

439 Conflict Resolution in Teams Slide 1 of 4
Stages in the Conflict Resolution Process Frustration. People are at odds, and competition or aggression ensues. Conceptualization and Orientation. Opponents identify the issues that need to be resolved. Interaction. Team members discuss and air the problems. Outcome. The problem is resolved.

440 Conflict Resolution in Teams Slide 2 of 4
Conflict Resolution Approaches Passive conflict resolution Win-win Structured problem solving Confronting conflict Choosing a winner Selecting a better alternative Preventing conflict

441 Conflict Resolution in Teams Slide 3 of 4
General Conflict Resolution Alternatives Avoidance involves letting things work themselves out without involving a leader. Defusion means smoothing ruffled feelings while getting the team project back on track. Confrontation involves injecting the leader into the conflict to find a solution.

444 Managing and Controlling Projects Slide 1 of 10
Managing Quality Improvement Projects Needs to be done in such a way that they will be coherent, thoughtful, and in alignment with organizational objectives. Project Charters Simple tools to help teams identify objectives, participants, and expected benefits from projects. Includes spaces for signatures to identify reporting relationships for planning purposes.

445 Managing and Controlling Projects Slide 2 of 10
Work Breakdown Structure (WBS) A tool for determining the tasks to complete a project. Used to help plan the project. Team members identify major tasks to complete the project, then subtasks and finally, minor tasks. With large projects, it is often best to develop a separate WBS for each of the major tasks, because separate individuals or groups may be involved in different tasks.

447 Managing and Controlling Projects Slide 4 of 10
Identifying Precedence Relationships WBS tasks are placed on individual note cards and precedence relationships are identified for all tasks. The note cards are placed in order on a large sheet of paper, and arrows are drawn between the tasks. Identifying Outcome Measures Should be developed from team charter. Should be done during the planning stage of a project, because some needed measures may not exist in current cost accounting systems. Should have preliminary and post hoc data so that baselining or intervention analysis can be performed.

Activity Network Diagram An activity network diagram is also known as a PERT (program evaluation and review technique) diagram or critical path (longest path in time from beginning to end) diagram and is used in controlling projects. Example of an PERT Diagram The figure on the next slide shows a PERT diagram with nodes and times. The nodes are circles and the times are given in days.

451 Managing and Controlling Projects Slide 8 of 10
Steps Used to Develop an Activity Network Diagram Using the inputs from a tree diagram listing tasks to be performed in the project, list all the tasks. Determine task times. Use the following simple formula: (t0 + 4tm + t)/6 to estimate task times where: t0 = Optimistic time estimate tm = Most likely time estimate t = Pessimistic time estimate Determine the precedence relationship between the tasks, that is, indicate which tasks depend on the completion of other tasks in the process.

452 Managing and Controlling Projects Slide 9 of 10
Steps Used to Develop an Activity Network Diagram (continued) Draw the network diagram. Compute early start and early finish times by working from left to right in the network. These are the earliest times that individual tasks can be started and finished. Compute late start and late finish times by moving from right to left in the network. These times are the latest times that tasks can possibly be started or finished. Compute slack times and determine the critical path. The critical path links activities with zero slack. Slack time = Late start – Early start

453 Managing and Controlling Projects Slide 10 of 10
Arrow Gantt Charts Tool used for controlling team projects. Most college textbooks treat PERT charts separately from Gantt charts. These differences are becoming inconsequential with many new software packages. Managing Multiple Projects At times, several projects occur simultaneously in a firm. Implementations have to be coordinated, because individuals should not be involved in too many teams in order for them to remain effective.

457 Statistical Fundamentals Slide 1 of 11
Statistical Thinking A decision-making skill demonstrated by the ability to draw to conclusions based on data. Based on three concepts All work occurs in a system of interconnected processes. All processes have variation (the amount of which tends to be underestimated). Understanding and reducing variation are important keys to success. Guides people to make decisions based on data, which needs to be done in business.

458 Statistical Fundamentals Slide 2 of 11
Why Do Statistics Sometimes Fail in the Workplace? Many times statistical tools do not create the desired result, because many firms fail to implement quality control in a substantive way. They prefer form over substance.

459 Statistical Fundamentals Slide 3 of 11
Reasons for Failure of Statistical Tools Lack of knowledge about the tools; therefore, tools are misapplied. General disdain for all things mathematical creates a natural barrier to the use of statistics. Cultural barriers in a company make the use of statistics for continual improvement difficult. Statistical specialists have trouble communicating with managerial generalists. Statistics generally are poorly taught, emphasizing mathematical development rather than application.

460 Statistical Fundamentals Slide 4 of 11
Reasons for Failure of Statistical Tools (continued) People have a poor understanding of the scientific method. Organizations lack patience in collecting data. All decisions have to be made “yesterday.” Statistics are viewed as something to buttress an already-held opinion rather than a method for informing and improving decision making. People fear using statistics because they fear they may violate critical statistical assumptions.

461 Statistical Fundamentals Slide 5 of 11
Reasons for Failure of Statistical Tools (continued) Most people don’t understand random variation resulting in too much process tampering. Statistical tools are often reactive and focus on effects rather than causes. People make mistakes with statistics, because of Type I error (producer’s risk) and Type II error (consumer’s risk). These erroneous decisions can result in high costs or lost future sales.

462 Statistical Fundamentals Slide 6 of 11
Understanding Process Variation All processes exhibit variation. Some variation can be controlled and some cannot. Two types of process variation Random Nonrandom Statistical tools presented here are useful for determining whether variation is random.

463 Statistical Fundamentals Slide 7 of 11
Random variation Random variation is centered around a mean and occurs with a consistent amount of dispersion. This type of variation cannot be controlled. Hence, we refer to it as “uncontrolled variation.” The statistical tools discussed in this chapter are not designed to detect random variation. Nonrandom variation Nonrandom or “special cause” variation results from some event. The event may be a shift in a process mean or some unexpected occurrence.

464 Statistical Fundamentals Slide 10 of 11
Process Stability Means that the variation we observe in the process is random variation (common cause) and not nonrandom variation (special or assignable causes). To determine process stability we use process charts. Process charts are graphs designed to signal process workers when nonrandom variation is occurring in a process. Sampling Methods Process control requires that data be gathered. Samples are cheaper, take less time and are less intrusive than 100% inspection.

465 Statistical Fundamentals Slide 11 of 11
Sampling Methods Random samples Randomization is useful because it ensures independence among observations. To randomize means to sample is such a way that every piece of product has an equal chance of being selected for inspection. Systematic samples Systematic samples have some of the benefits of random samples without the difficulty of randomizing. Sampling by Rational Subgroup A rational subgroup is a group of data that is logically homogenous; variation within the data can provide a yardstick for computing limits on the standard variation between subgroups.

466 Process Control Charts Slide 1 of 20
Statistical Process Control Charts Tools for monitoring process variation. The figure on the following slide shows a process control chart. It has an upper limit, a center line, and a lower limit. Variables and Attributes To select the proper process chart, we must differentiate between variables and attributes. A variable is a continuous measurement such as weight, height, or volume. An attribute is the result of a binomial process that results in an either-or-situation.

469 Process Control Charts Slide 4 of 20
Central Requirements for Properly Using Process Charts 1. You must understand the generic process for implementing process charts. You must know how to interpret process charts. You need to know when different process charts are used. You need to know how to compute limits for the different types of process charts. 2. 3. 4.

470 Process Control Charts Slide 5 of 20
A Generalized Procedure for Developing Process Charts Identify critical operations in the process where inspection might be needed. These are operations in which, if the operation is performed improperly, the product will be negatively affected. Identify critical product characteristics. These are the aspects of the product that will result in either good or poor function of the product. Determine whether the critical product characteristic is a variable or an attribute.

471 Process Control Charts Slide 6 of 20
A Generalized Procedure for Developing Process Charts (continued) Select the appropriate process control chart from among the many types of control charts. This decision process and types of charts available are discussed later. Establish the control limits and use the chart to continually monitor and improve. Update the limits when changes have been made to the process.

472 Process Control Charts Slide 7 of 20
Understanding Control Charts A process chart is nothing more than an application of hypothesis testing where the null hypothesis is that the product meets requirements. An X-bar chart is a variables chart that monitors average measurement. Control charts draw a sampling distribution rather than a population distribution. Control charts make use of the central limit theorem, which states that when we plot sample means, the sampling distribution approximates a normal distribution.

473 Process Control Charts Slide 8 of 20
X-bar and R Charts The X-bar chart is a process chart used to monitor the average of the characteristics being measured. To set up an X-bar chart Select samples from the process for the characteristic being measured. Then form the samples into rational subgroups. Next, find the average value of each sample by dividing the sums of the measurements by the sample size and plot the value on the process control X-bar chart.

474 Process Control Charts Slide 9 of 20
X-bar and R Charts (continued) The R chart is used to monitor the dispersion of the process. It is used in conjunction with the X-bar chart when the process characteristic is a variable. To develop an R chart Collect samples from the process and organize them into subgroups, usually of three to six items. Next, compute the range, R, by taking the difference of the high value in the subgroup minus the low value. Then plot the R values on the R chart.

475 Process Control Charts Slide 11 of 20
Interpreting Control Charts Before introducing other types of process charts, we discuss the interpretation of the charts. The figures in the next several slides show different signals for concern that are sent by a control chart, as in the second and third boxes. When a point is found to be outside of the control limits, we call this an “out of control” situation. When a process is out of control, the variation is probably no longer random.

Control Chart Evidence for Investigation Figure 12.10

478 Process Control Charts Slide 14 of 20
Implications of a Process Out of Control If a process loses control and becomes nonrandom, the process should be stopped immediately. In many modern process industries where just-in-time is used, this will result in the stoppage of several work stations. The team of workers who are to address the problem should use a structured problem solving process.

479 Process Control Charts Slide 15 of 20
X and Moving Range (MR) Charts for Population Data At times, it may not be possible to draw samples. This may occur because a process is so slow that only one or two units per day are produced. X chart. A chart used to monitor the mean of a process for population values. MR chart. A chart for plotting variables when samples are not possible. If data are not normally distributed, other charts are available.

480 Process Control Charts Slide 16 of 20
g and h Charts A g chart is used when data are geometrically distributed h charts are useful when data is hypergeometrically distributed. If a histogram of data appears like either of these distributions, you may want to use either an h or a g chart instead of an X chart. Figure 12.13

481 Process Control Charts Slide 17 of 20
Median Charts Many be used when it is too time consuming or inconvenient to compute subgroup averages or when there is concern about the accuracy of computed means. Small sample sample sizes are generally used like the x-bar chart. Equations for computing the control limits are: = Mean of medians = sum of the medians/number of medians

482 Process Control Charts Slide 18 of 20
x-bar and s Charts When dispersion of the process is of particular concern the s (standard deviation) chart is used in place of the R chart. Different formulas are used to compute the limits for the x-bar chart.

483 Process Control Charts Slide 19 of 20
Other Control Charts Moving Average Chart. The moving average chart is an interesting chart that is used for monitoring variables and measurement on a continuous scale. The chart uses past information to predict what the next process outcome will be. Using this chart, we can adjust a process in anticipation of its going out of control. Cusum Chart. The cumulative sum, or cusum, chart is used to identify slight but sustained shifts in a universe where there is no independence between observations.

485 Some Control Charts Concepts for Variables Slide 1 of 4
Choosing the Correct Variables Control Chart Obviously, it is key to choose the correct control chart. Figure in the textbook shows a decision tree for the basic control charts. This flow chart helps to show when certain charts should be selected for use. Corrective Action. When a process is out of control, corrective action is needed. Corrective action steps are similar to continuous improvement processes.

486 Some Control Charts Concepts for Variables Slide 2 of 4
Corrective Action (continued) Correction action steps : Carefully identify the problem. Form the correct team to evaluate and solve the problem. Use structured brainstorming along with fishbone diagrams or affinity diagrams to identify causes of the problem. Brainstorm to identify potential solutions to problems. Eliminate the cause. Restart the process. Document the problem, root causes, and solutions. Communicate the results of the process to all personnel so that this process becomes reinforced and ingrained in the organization.

487 Some Control Charts Concepts for Variables Slide 3 of 4
How Do We Use Control Charts to Continuously Improve? One of the goals of the control chart user is to reduce variation. Over time, as processes are improved, control limits are recomputed to show improvements in stability. As upper and lower control limits get closer and closer together, the process improving. Two key concepts: The focus of control charts should be on continuous improvement. Control chart limits should be updated only when there is a change to the process. Otherwise any changes are unexpected.

488 Some Control Charts Concepts for Variables Slide 4 of 4
Tampering With the Process One of the cardinal rules of process charts is that you should never tamper with the process. You might wonder, Why don’t we make adjustments to the process any time the process deviates from the target? The reason is that random effects are just that—random. This means that these effects cannot be controlled. If we make adjustments to a random process, we actually inject nonrandom activity into the process.

489 Process Capability Slide 1 of 11
Process Stability and Capability Once a process is stable, the next emphasis is to ensure that the process is capable. Process capability refers to the ability of a process to produce a product that meets specifications. Six-sigma program such as those pioneered by Motorola Corporation result in highly capable processes.

490 Process Capability Slide 2 of 11
Six-Sigma Quality Figure 12.20

491 Process Capability Slide 3 of 11
Process Versus Sampling Distribution To understand process capability we must first understand the differences between population and sampling distributions. Population distributions are distributions with all the items or observations of interest to a decision maker. A population is defined as a collection of all the items or observations of interest to a decision maker. A sample is subset of the population. Sampling distributions are distributions that reflect the distributions of sample means.

492 Process Capability Slide 4 of 11
Capability Studies Now that we have defined process capability, we can discuss how to determine whether a process is capable. That is, we want to know if individual products meet specifications. There are two purposes for performing process capability studies: 1. To determine whether a process consistently results in products that meet specifications 2. To determine whether a process is in need of monitoring through the use of permanent process charts.

493 Process Capability Slide 5 of 11
Capability Studies (continued) Process capability studies help process managers understand whether the range over which natural variation of a process occurs is the result of the system of common (or random) causes.

494 Process Capability Slide 6 of 11
Capability Studies (continued) Five steps in performing process capability studies: 1. Select a critical operation. These may be bottlenecks, costly steps of the process, or places in the process where problems have occurred in the past. 2. Take k samples of size n, where x is an individual observation. Where 19 < k < 26 If x is an attribute n > 50, (as in the case of a binomial) Or if x is a measurement 1 < n < 11 (Note: Small sample sizes can lead to erroneous conclusions.)

495 Process Capability Slide 7 of 11
Capability Studies (continued) Five steps in performing process capability studies: 3. Use a trial control chart to see whether the process is stable. 4. Compare process natural tolerance limits with specification limits. Note that natural tolerance limits are three standard deviation limits for the population distribution. This can be compared with the specification limits.

496 Process Capability Slide 8 of 11
Capability Studies (continued) Five steps in performing process capability studies: 5. Compute capability indexes: To compute capability indexes, you compute an upper capability index (Cpu), a lower capability index (Cpl), and a capability index (Cpk). The formulas are:

497 Process Capability Slide 9 of 11
Capability Studies (continued) Although different firms use different benchmarks, the generally accepted benchmarks for process capability are 1.25, 1.33, and 2.0. We will say that processes that achieve capability indexes (Cpk) of: 1.25 are capable 1.33 are highly capable 2.0 are world-class capable (six sigma)

498 Process Capability Slide 10 of 11
Ppk Population capability index Used when data is not arranged in subgroups, but is only available as population data. Formulas:

499 Process Capability Slide 11 of 11
The Difference Between Capability and Stability Once again, a process is capable if individual products consistently meet specifications. A process is stable if only common variation is present in the process. It is possible to have a process that is stable but not capable. This would happen where random variation was very high. It is probably not so common that an incapable process would be stable.
