It's not bad

I already knew what six sigma was and I already had a basic grasp of statistical concepts. I got what I expected from the book, a high level overview of six sigma.

This book is about 160 pages long, I think the author could have easily trimmed some fat and fluff and condensed it to less then 100 pages.

Overall, I'm glad I bought the book, it's inexpensive and I feel I've gotten my money's worth.

Good Introduction for those who are confused about Six Sigma

I wanted to know about Six Sigma. I read some articals, but did not get a good picture of Six Sigma. This book is quite readable, interesting and provides a good introduction to Six Sigma. I recommend it to any one as the first book towards Six Sigma initiative.

Not credible

Thought I would get a good overview of the topic, to understand what it is, so I can decide when to dive in deeper.

But after reading the first two chapters the author has lost total credibility, and I won't waste my time on the rest of the book. It talks all about the wonderful savings Six Sigma will give you, and totally ommits that there is cost involved in doing it. If done well, yes there's positive bottom-line impact, but especially as a manager I want to know what the ROI is, and not just get glory words on the upside, but also a realistic view of the downside.

What killed it for me was the side bar that assumed that if a employee costs $50K, and her activities produce $100K in revenue that the ROI of having this employee is 100%!! If the activities would have produced $100K in net profit, then this would be more accurate. So lets get the basics right, so that we have credibility to talk about the rest.
