Quality Control Tools A committee for developing QC tools affiliated with JUSE was set up in April 1972. Their aim was to develop QC techniques for use by managerial level and staff. This committee was headed by Yoshinobu Nayatani and they met regularly. In January 1977 the committee announced the results of its research in the form of a new set of methods called 'The Seven New QC Tools’. (http://www.iqd.com/pfttools.htm)

Introduction Cause and Effect Diagrams Check Sheet Control Charts The Perform Quality Control process of the Project Quality Management knowledge area has several quality control tools and techniques that are also used in the Perform Quality Assurance process. The quality control tools and techniques discussed in this article are: Cause and Effect Diagrams Check Sheet Today, QC is still undergoing a major transformation. Through the evolution of TQM, all people in every dept and at every level have been and are being involved. Initially, QC was thought to be the responsibility solely of production dept through the inspection process. TQM now has become everyone’s business from Planning to Engineering to Marketing, and to direct Customer Service. (Nayatini 1) To assist in meeting the demands of this transformation,the Seven New QC Tools have been created. These have also been referred to as the N7’s or Seven Mgt. Tools for QC. Control Charts Histogram Pareto Chart Scatter Diagram Stratification By: Mark Rigor Mirondo

Cause and Effect Diagram Fishbone Diagram Also Called: Cause-and-Effect Diagram, Ishikawa Diagram Variations: cause enumeration diagram, process fishbone, time-delay fishbone, CEDAC (cause-and-effect diagram with the addition of cards), desired-result fishbone, reverse fishbone diagram Description The fishbone diagram identifies many possible causes for an effect or problem. It can be used to structure a brainstorming session. It immediately sorts ideas into useful categories. When to Use a Fishbone Diagram When identifying possible causes for a problem. Especially when a team’s thinking tends to fall into ruts. Affinity Diagrams Relations Diagrams Tree Diagrams Matrix Diagrams Arrow Diagrams Process Decision Program Charts Matrix data analysis We will spending most of our time on the first 6. Before we actually get started, we need to look at the: By: Mark Rigor Mirondo

When to Use a Check Sheet Also called: defect concentration diagram Description A check sheet is a structured, prepared form for collecting and analyzing data. This is a generic tool that can be adapted for a wide variety of purposes. When to Use a Check Sheet When data can be observed and collected repeatedly by the same person or at the same location. When collecting data on the frequency or patterns of events, problems, defects, defect location, defect causes, etc. When collecting data from a production process. Their intent was to develop tools that would provide methods of organizing verbal data. They wanted to create a complete “Design Approach”. The established Basic 7 tools were very effective, however they were primarily focused on numerical data. For example, if a washing machine is redesigned. The customers don’t like the new control panel, style, and color. These statements are not expressed in numerically , but verbally. These statements are expressions of data, but only in a verbal form. (Nayatini 3) So in conjunction in with the B7, the N7 can dramatically increase the the effectiveness of many TQM activities. The two sets of tools can greatly assist the promotion of Total Quality. By: Mark Rigor Mirondo

Control Charts Control Chart Also called: statistical process control Description The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit and a lower line for the lower control limit. These lines are determined from historical data. By comparing current data to these lines, you can draw conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation). Flow Charts - pictorial representation showing all of the steps of a process Run Charts - used to analyze processes according to time or order Histograms - bar graphs with frequency intervals Pareto Diagrams - 80/20 histograms for identifying and prioritizing problems Cause and Effect Diagrams - fishbone diagrams Scatter Diagrams - Identifies the possible relationship between the changes observed in two different sets of variables. Control Charts - used to determine whether a process will produce a product or service with consistent measurable properties By: Mark Rigor Mirondo

When to Use a Control Chart Control Charts When to Use a Control Chart When controlling ongoing processes by finding and correcting problems as they occur. When predicting the expected range of outcomes from a process. When determining whether a process is stable (in statistical control). When analyzing patterns of process variation from special causes (non-routine events) or common causes (built into the process). When determining whether your quality improvement project should aim to prevent specific problems or to make fundamental changes to the process. The Organizational Reform establishes a system wide Culture that should result in stimulating people to think for themselves. This culture should result in a workforce that is constantly “Thinking TQM” and being “Creative with TQM”. (Nayatini 10) By: Mark Rigor Mirondo

Histogram Description A frequency distribution shows how often each different value in a set of data occurs. A histogram is the most commonly used graph to show frequency distributions. It looks very much like a bar chart, but there are important differences between them. When to Use a Histogram When the data are numerical. When you want to see the shape of the data’s distribution, especially when determining whether the output of a process is distributed approximately normally. This shows how the N7 and the B7 complement each other in solving quality-related problems. Facts -> to Data! Do people provide data in numerical form or verbally? (How do you?) Information - This is the most IMPORTANT GOAL!!! Without the info, there will be no KNOWLEDGE gained which is required for achieving our goal! (Nayatini 4) Source: Nayatani, Y., The Seven New QC Tools (Tokyo, Japan, 3A Corporation, 1984) By: Mark Rigor Mirondo

When to Use a Pareto Chart Also called: Pareto diagram, Pareto analysis Variations: weighted Pareto chart, comparative Pareto charts Description A Pareto chart is a bar graph. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant. When to Use a Pareto Chart When analyzing data about the frequency of problems or causes in a process. When there are many problems or causes and you want to focus on the most significant. The N7 are used for promoting Total Quality. The goals for TQM are: Ensuring company fulfills obligations, Securing profits, Developing people (Nayatini 9) The N7 enhance the capabilities of every employee. It has a direct impact on developing the workforce. At the same time, the effectiveness and efficiency is greatly enhanced which results directly on the bottom-line. By: Mark Rigor Mirondo

When to Use a Scatter Diagram Also called: scatter plot, X–Y graph Description The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve. The better the correlatin, the tighter the points will hug the line. When to Use a Scatter Diagram When you have paired numerical data. When your dependent variable may have multiple values for each value of your independent variable. The N7 will lead to Organizational Reform system-wide. These keys lead to a greater set of skills. The most important being, the ability to be proactive in anticipating future problems. (Nayatini 10) By: Mark Rigor Mirondo

When to Use Stratification Description Stratification is a technique used in combination with other data analysis tools. When data from a variety of sources or categories have been lumped together, the meaning of the data can be impossible to see. This technique separates the data so that patterns can be seen. The N7 are techniques for untangling the intricate relationships among the different variables of a problem. Using the N7 makes it easy to clarify the situation, establish a plan, and get to the root cause of the the problem. It also makes it easier to explain the situation and get “buy-in” with their cooperation. (Nayatini 6) When to Use Stratification Before collecting data. When data come from several sources or conditions, such as shifts, days of the week, suppliers or population groups. When data analysis may require separating different sources or conditions.
