Subjects and activities for the class A. Basic TQM tools B. Quality innovators: Shewhart, Deming, Juran, Isikawa C. Memory Jogger II , pp. vi-vii and instructor-provided overviews of the tools from the Coach’s Guide , pp. xxvii and 217. D. Memory Jogger II , pp. 150-155, working in teams E. Discussion of class members’ experiences with groups. II. Total Quality Management (TQM): Concepts and Principles There are seven basic quality control tools and seven management and planning tools. These are used to identify problem areas, structure data collection, analyze data, focus problem solving efforts, and disseminate information throughout the organization. A. Seven basic QC tools These are used to analyze numerical data. Most experts advocate teaching them at all levels of the organization, but most especially with first line supervisors and workers. We shall learn and apply each of these tools in this class. The control chart will get much less attention than in prior semesters, but you will receive an introduction to it. The time I found for you to work more in class on the group projects came from the control chart material. 1. Check sheet 2. Pareto chart 3. Cause and effect diagram 4. Histogram 5. Scatter diagrams 6. Graphs 7. Control charts B. Seven management and planning tools We shall learn about and use most, but not all of these seven tools during the class. 1. Affinity diagram

Quality Innovators Some of the names of the founders of TQM and CQI should be familiar; now we learn more about the people behind them. We take up four quality innovators: Shewhart, Deming, Ishikawa, and Juran. There are others, but this is not a course on the history of quality improvement theorists and practitioners. A. Walter A. Shewhart Shewhart developed the control chart concept, a simple version of one is shown in the graph below and to the right. A control chart specifies the upper and lower limits of statistically acceptable variation in a process. Shewhart found that variation comes from two sources: random variation that cannot be controlled, called “chance cause variation,” or “ common cause” variation. Other causes of variation could
