DOM 511 :Operations Management Practice 1- Overview By: Munyao-mulwa UoN School of Business 2016
What is Operation Management? Typical Operations Manufacturing: Getting the products a company makes to an agreed specification, in due time Transport: Ensuring the transport runs to an agreed schedule Retailing: Pushing the merchandise through the store to the consumer Service: Providing satisfactory, according to an agreed schedule, the service to the customer Operations Manager: The supplier of products or services required by the market place Utilises the organization resources to meet the product or service specifications efficiently & effectively
Operations Management Definition Applying analytical tools and frameworks to improve business processes that cross internal functional boundaries 4 4
Operations Management Definition OM is the science & art of ensuring that goods & services are created & delivered successfully to customers. Applying the principles of OM entails a solid understanding of people, processes, & how they are integrated within a business to create value 4 4
From General Management To Operations Management Traditional Management paradigm revolves around planning, organizing, directing & controlling OM is the only means by which managers can directly affect the value provided to all stakeholders – customers, employees, investors & society hence OM is a more diverse discipline & spans multiple functional areas 4 4
Activities of OM Discipline Layout planning - to give smooth and effective flow of customers, work in process etc ( process design) Making sure that all staff can contribute to the company’s success (job design); Avoiding running out of products for sale (inventory management); Monitoring and enhancing quality of service to customers (Quality management); 4 4
Activities of OM Discipline Locating stores of an appropriate size in the most effective place (supply network design); Arranging for the delivery of products to stores (Supply chain management) Coping with fluctuations in demand (Capacity management) Maintaining cleanliness and safety of storage area ( failure prevention); 4 4
Activities for OM discipline Understanding the needs of customers, measuring customer satisfaction & using the information to develop new & improved goods & services Using information about customers, goods/services, operations, suppliers, employees etc to make better decisions 4 4
Activities for OM discipline Exploiting technology to design goods & services that respond rapidly & flexibly to customer requirements & improve productivity (product Design) Continually learning from co-workers, competitors & customers & adapting the organization to global & environmental changes (Operations Improvement) 4 4
OM Discipline OM principles are not complicated for they constitute the “basics” of everyday life eg Respect for customer experience Focus on the dynamics of demand Recognition that experience is delivered by people etc >>The fundamental purpose of OM is to deliver ever-improving value to customers through the continuous improvement of overall company performance & capabilities 4 4
Operations Decision Making Marketplace Corporate Strategy Operations Strategy Operations Management Marketing Strategy Finance Strategy People Plants Parts Processes Planning and Control Production System Materials & Customers Input Products & Services Output 5 5
OM Involves Managing Transformations Process (Value Adding) Input Output Transformation is enabled by The 5 Ps of OM: People Plants Parts Processes Planning and Control 6 6
Why Do customers buy products /Services? Value = quality / price How can an organization increase customer value? 4 4
OM’s Transformation Role To add value Increase product value at each stage Value added is the net increase between output product value and input material value Provide an efficient transformation Efficiency – perform activities well at lowest possible cost 7 7
Transformations Physical--manufacturing Locational--transportation Exchange--retailing Storage--warehousing Physiological--health care Informational--telecommunications 7 7
Greater value than inputs Systemic Approach Greater value than inputs Requirements Inputs Material Machines Labor Management Capital Outputs Goods Services Transformation Process Feedback Feedback Push or Pull?
SIPOC Model Inputs Outputs Process Suppliers Clients (+ Owner) Interfaces Management Inputs Outputs Process (+ Owner) Suppliers Clients Responsible for “smooth” operation The output has higher value than the input: VALUE CHAIN
Operations Function & its Environment Product / Services Suppliers Other functions (Purchasing, Distribution, R&D…) Production Technical Core Resources Human Marketing Sales Order Labor Force Physical Transformation Activity Finance Investments in Equipment
Operations as the Technical Core Finance/Accounting Human Resources Marketing Suppliers Production and Inventory data Capital budgeting requests Capacity expansion and Technology plans Budgets Cost analysis Capital investments Stockholder requirements Orders for materials Production and delivery Schedules Quality Requirements Design/ Performance specs Material availability Quality data Delivery schedules Designs Product/Service Availability Lead-time estimates Status of order Sales forecasts Customer orders Customer feedback Promotions Personnel needs Skill sets Performance evaluations Job design/work measurement Hiring/firing Training Legal requirements Union contract negotiations
Trends in OM Service sector growing to 50-80% Global competitiveness Demands for higher quality Huge technology changes Time based competition Work force diversity
Why OM? For long-run success companies must place much importance on their operations The 1950-1960 era was the U.S. golden era where primary opportunities were marketing The 1970-1980 U.S. companies experienced a large decline in productivity growth – international firms began to challenge in many markets The 1970-1980 era saw U. S. firms lagging behind in methods and processes The resurgence of American business in the 1990’s capitalized on improved operations
Today’s OM Environment Customers demand better quality, greater speed, and lower costs Companies implementing lean systems concepts – a total systems approach to efficient operations Recognized need to better manage information using ERP and CRM systems Increased cross-functional decision making
OM in Practice OM is the most diverse organizational function Manages the transformation process OM has many faces and names such as; Chief Operating Officer, V. P. operations, Director of supply chain, Manufacturing manager Plant manger, Quality specialist, etc. All business functions need information from OM in order to perform their tasks

Development Summary Time-Based Competition 1990s Supply chain Management 1990s Electronic Commerce 2000s Offshoring, Outsourcing & flattening of the world- 2000s Talent Age Now
Offshoring Building, acquiring or moving of process capabilities from a domestic location to another location while maintaining ownership & control Categories of foreign factories Offshore factories – established to gain access to low wages & reduce costs like trade tariffs. Most common Outpost factories – established to gain access to local employee skills & knowledge eg software engineering Server factories - established to supply specific national or regional markets eg coca cola bottling plants Source factories – established to gain access to low-cost production but have expertise to design & produce a component part
Offshoring Categories of foreign factories Contributor factories – established to serve a local market and conduct activities like product design & customization Lead factories – to innovate & create new processes, products & technologies eg HP established an offshore factory in 1970 in singapore
Issues to Consider in Offshoring Dcns Labour talent pool Low labor costs Lower import duties & fees Lower capital costs Grow global market share Avoid national currency fluctuations Preempt competitors from entering global market(s) Hire worldwide skills & knowledge workers Build relationships with suppliers Learn foreign markets & cultures Develop secure sources of supply & reduce risks
Current Issues in OM Coordinating the relationships between mutually supportive but separate organizations. Dramatic surge in the outsourcing of parts and services that had previously been produced internally. New breed of contract manufacturers that specialize in performing focused manufacturing activities now exists Companies considering outsourcing other major corporate functions such as information systems, product development and design, engineering services, packaging, testing, and distribution..
Current Issues in OM Optimizing global supplier, production, and distribution networks. The implementation of global enterprise resource planning systems, now common in large companies, has challenged managers to use all of this information. Requires a careful understanding of where centralized control and autonomy should be to optimally control such resources as inventory, transportation, and production equipment
Current Issues in OM Increased co-production of goods and services. The Internet has opened new ways for the customer to interact directly with a firm. Simple direct entry and monitoring of orders is now possible Intelligent use of information technology will allow the shedding of entire layers of inefficient customer-oriented functions within a firm, resulting in dramatic reductions in cost while actually improving service to the customer
Current Issues in OM Managing customer touch points As companies strive to become superefficient, they often scrimp on customer support personnel (and training) required to effectively staff service departments, help lines, and checkout counters Making resource utilization decisions must capture the implicit costs of lost customers as well as the direct costs of staffing
Current Issues in OM Raising senior management awareness of operations as a significant competitive weapon Many senior executives entered many organizations through finance, strategy, or marketing and built their reputations on work in these areas, and as a result often take operations for granted. Executives of profitable companies such as Toyota, Dell, Taco Bell, and Southwest Airlines have creatively used operations management for competitive advantage

Productivity improves when firms ; Output Input Productivity improves when firms ; Become more efficient Downsize Expand Retrench Achieve breakthroughs
Productivity Partial measures Multi-factor measures Total measure output/(single input) Multi-factor measures output/(multiple inputs) Total measure output/(total inputs) 17 17
Productivity Productivity Analysis Trend analysis: Studying productivity changes for the firm over a period of time. Horizontal analysis: Studying productivity in comparison with other firms of same size and engaged in similar business. Vertical analysis: Studying productivity in comparison with other industries and other firms of different sizes in the same industry. 17 17
Measures of Productivity Single-factor Output Output Output Output measures Labor Machine Capital Energy All-factors Output measure All inputs
Example 10,000 Units Produced Sold for $10/unit 500 labor hours Labor rate: $9/hr Cost of raw material: $5,000 Cost of purchased material: $25,000 What is the labor productivity? 18 18
What are the factors that affect productivity? Training Methods Technology Management
Example--Labor Productivity 10,000 units/500hrs = 20 units/hour ... ... or we can arrive at a unitless figure (10,000 unit*$10/unit)/(500hrs*$9/hr) = 22.22 19 19
