Pyzdek's guide to SPC.: applications and special topics
Finally, a book about HOW TO USE statistical process control (SPC) to improve quality in a wide variety of real-world situations, written by the instructor for the American Society for Quality Control's SPC courses nationally. Are you faced with things like short runs; toolwear & other built-in out-of-control situations; sampling questions: how many? how often? how should I form the subgroups?; processes you knew were in-control even though the control charts showed them to be out-of-control; measurement systems that never get the same result twice; processes with lousy Cpk's but that never produce a single reject; processes with so many important variables a supercomputer couldn't process all of the data; great manufacturing operations but awful service processes, & no known way of applying SPC to them; multiple-head fillers, multiple-cavity molds or other multiple-stream processes that require too many charts; SPC teams that get bogged down studying the food in the cafeteria, etc.; many SPC projects, but no true quality improvement plan? If any of this is familiar, then you NEED this book. One reviewer said of this book: "It is similar in content to parts of the SQC handbook from AT&T...but provides many more choices & the details for use."
