Creating a universal language for problem solving, The Practical Application of the Process Capability Study: Evolving from Product Control to Process Control delineates the process capability study, a powerful tool that, when understood and implemented, provides benefits to every department within a manufacturing organization. With easy to read, step-by-step flow diagrams on how to perform process capability studies and measurement process analyses, the book’s coverage includes:
The benefits of statistical process control over statistical product control
Real-world industrial examples and case studies illustrating how to use the techniques
Ways for management to determine if the investment in process capability studies is providing an appropriate return
Methods to correct lack of stability and capability once either condition has been identified, such as the ANOVA technique and the simple three-factor designed experiment
A flow chart that enables machine operators to execute a process capability study without interfering with productivity
A great deal of information is available on the technical concepts of the process capability study, much of it emphasizing the mathematics. Unfortunately, concentrating on the math and fine distinctions, such as the difference between alpha- and beta-type errors, has created barriers preventing many from fully appreciating the basic concepts, the simplicity, and the usefulness of the tool. This book shows you how to use the process capability study to increase return on investment from your statistical process control/Six Sigma effort and make your company more competitive.
Reviews
… the book has many great examples and case histories that provide insight into the methods the author has employed over at least the past 30 years. …

The techniques described in this book are essential for the long-term survival of any manufacturerice provider.

The measurement process analysis technique (MPA) helped us realize many critical product characteristics were far more capable (less variation) than we previously thought. [Doug’s book] reduced inspection, rework, and scrap and overall improved our competitiveness.
