Editorial Review:
Reducing the variation in process outputs is a key part of process improvement. For mass produced components and assemblies, reducing variation can simultaneously reduce overall cost, improve function and increase customer satisfaction with the product. The authors have structured this book around an algorithm for reducing process variation that they call "Statistical Engineering." The algorithm is designed to solve chronic problems on existing high to medium volume manufacturing and assembly processes. The fundamental basis for the algorithm is the belief that we will discover cost effective changes to the process that will reduce variation if we increase our knowledge of how and why a process behaves as it does. A key way to increase process knowledge is to learn empirically, that is, to learn by observation and experimentation. The authors discuss in detail a framework for planning and analyzing empirical investigations, known by its acronym QPDAC (Question, Plan, Data, Analysis, Conclusion). They classify all effective ways to reduce variation into seven approaches. A unique aspect of the algorithm forces early consideration of the feasibility of each of the approaches. Benefits: The CD-ROM included contains case studies, chapter exercises, chapter supplements, and six appendices.

Statistical Engineering  2006-03-28
This is a great book! I have been doing industrial problem solving for nearly ten years and I can tell you that you won't find strategies and tools like this in a Six Sigma seminar.
Please see JQT review 2005-11-02
I reviewed this book very favorably for the Journal of Quality Technology in the October 2005 issue. This review is freely available to the public.
I am not allowed to post the URL, but a quick search on ASQ Journal of Quality Technology should get you there.

I NEED TO KNOW WHERE BOTH MY ITEMS ARE. I HAVE ONLY RECEIVED
ONE. PLEASE EXPEDIATE AND ADVISE.
Must read 2005-06-24
This is NOT a typical book on statistical tools. It is a strategy book on how to search for cost-effective changes to reduce variation using empirical means (i.e. observation and experiment). The uniqueness of this book:
(1) Summarizes the seven ways to reduce variation so we know the goal of the data gathering and analysis
(2) Present analysis results using graphs instead of P-value.
(3) It integrates Taguchi, Shainin methods and classical statistical approach.
It is a must read for those who are in the business of reducing variation using data, in particular for the Six Sigma Black Belts and Master Black Belts. Don't forget to read the solutions to exercises and supplementary materials to each chapter on the enclosed CD-ROM.
