Introduction to Control Charts

內容大綱
Statistical Process Control for Managers is an eight-chapter book published by Business Expert Press in 2014 and written by Victor E. Sower, professor emeritus of operations management at Sam Houston State University. The book provides a conceptual approach to using statistical process control (SPC) to inform and improve decision-making around business processes and quality improvement. The author reviews the basic methods of SPC and provides practical guidance for using specific tools. He incorporates real-world examples throughout the book and ends each chapter with a summary of key points, as well as questions for managers to ask when applying the concepts to their own organizations. In Chapter 3, Introduction to Control Charts (20 pages), the author demonstrates how to read and create a map of a business process. Using an individual control chart (I-chart), he explains the chart elements and how software programs can be used to create them. He explains how to determine whether or not a process is in control by analyzing patterns on a control chart and reviews single point rules, run rules, and zone rules, as well as nonrandom patterns. He offers insight on how to react to a process out of control by creating and implementing an action plan.
