Query: Six Sigma is the way to go, but not with this book!

I have just finished reading Mario Perez-Wilson's 396 pages of Six Sigma consulting propaganda. In fact, an entire chapter is devoted to promoting Advanced Systems Consultants-Perez-Wilson's consulting firm-as the best, if not only, way to achieve Six Sigma in an organization. A memorial to the overarching ego of Mr. Perez-Wilson, "Six Sigma: Understanding the Concept, Implications and Challenges" is repetitive, poorly edited, and gives only enough information about Six Sigma to allow the reader to engage in cocktail party small talk.
