Twenty Things You Need to Know

by Donald J. Wheeler

An alternate title for this book might have been "Lessons Learned from a Lifetime of Data Analysis." Drawing on 40 years of study, practice, instruction, and consultation, this book provides brief answers to many of the commonly occurring questions that arise when people begin to use process behavior charts. While the first chapter recaps some material from Understanding Variation, the rest complement and complete the message of that book. In every case the objective was to enable you to better and more easily use process behavior charts to get the most out of your processes and operations. Since not all sources of information about SPC are equally reliable, some of the chapters are, of necessity, focused on mistakes and misinformation that are currently in circulation. In the interest of completeness, these chapters also include enough of the background material to justify the answer given. In addition, citations are given for those who wish to delve more deeply into any particular topic.

Reviews

[Andrea Horst · Rating 4 out of 5]

Nice practical review of SPC and statistical analysis. Meant to be a companion to Explaining Variation.

[Cedric Chin · Rating 4 out of 5]

A solid addition to the canon of statistical process control. (This is a fancy way of saying: the book teaches you how to become data driven.)

My only recommendation is that you read this after Understanding Variation, and after at least a few weeks of attempting to use XmR charts in a real world business.

I have never been disappointed by a book by Donald Wheeler. This book is not terribly detailed but very well written. Highly recommend.
