Query: Where's the beef?

I agree with the complaints of many of the other reviewers of this book. I believe that Six Sigma truly is a powerful industrial/business tool. Unfortunately this book reads like it was designed as a brochure for managers considering implementation of quality control programs for their companies. There are some basic Six Sigma tenets outlined, but in disappointingly little depth. It was especially frustrating to wade through all of the RAH-RAH name-dropping of corporations and CEOs to get to any real information. I did not expect to be a 'black belt' when I finished this book, but all I really came away with was a cursory introduction to the Six Sigma approach and the sense that I had just been delivered a thinly veiled sales pitch.
