Hidden Gem

I can't believe I was only introduced to this in a graduate level class, under the humble (and quite vague) disguise of "modern enterprise systems". That said, this book has tremendous applications beyond IE courses. Astonishing and empowering...and I hope it really catches on for those who can handle a transformation free of charge courtesy of Wheeler....I guess IE's have a strong advantage with this one, so it'll be our little secret in the meantime...

Interpreting data is about the patterns, not the points

This is not a book for people looking for the technical detail of data analysis or statistical process control. The pearl in this book is the message that interpreting your data (such as KPIs or performance measures) is about looking at patterns, not at individual points. It's a book that can be read by people not interested in the technical stuff (such as managers or executives) - and it *should* be read by these people. We have to move beyond the days of comparing this month to last month to judge business performance, and this book is a great step in the right direction!

A must for Six Sigma DFSS

I learned statistics back in the university then never applied concepts and after some 10 years I was challenged to undertake basic statistics matters in the way of learning Six Sigma. This book is very focused on the variation and the graphical interpretation of data. Yuo may read this book over a weekend then attack Six Sima stats without pain.

A Practioners Guide

This is not for the Acacdemic, It doesn't explain the satistical mathematics behind the techniques, but it is a good solid recipe book with solid advice on understanding the nature of variation and application of process control. Get's right to the heart of the practice.
Good job.

Great to help an organization start to think about variation

While I agree with a couple of other reviews that this book is high-level and superficial, this is an excellent resource to start discussions about variation. In an organization where we are new to process improvement or even considering the impact or sources of variation, this book is essential. It is a quick read and great for management.
