Six Sigma for the Next Millenium [PDF ebook] 
A CSSBB Guidebook

This book follows the ASQ Certified Six Sigma Black Belt (CSSBB) Body of Knowledge exactly and is designed to walk the reader through at a medium-level of detail. Organization of the material is completely straightforward— broken down into ‘bite-size’ chunks with the student in mind. While a plethora of books claim some relation to Six Sigma, unfortunately very few of them support the body of knowledge explicitly.The author supplies the Black Belt candidate with enough information to pursue the CSSBB examination aggressively, with the material in the book and also the ancillary works referenced. At the end of each chapter are one or two titles for further reading, works that the author owns personally and uses for both work and formal examination study.The book can serve as an intense, high-speed tutorial for the CSSBB examination, a reference for the working Black Belt, or a resource to find further reading. Trainers could use it in their Black Belt certification preparation classes.
