My view is that Pyzdek's book is a nice basic overview to six-sigma. Something for greenbelts but hardly the coverage necessary for blackbelts. Blackbelts, by definition, need in depth coverage with excellent software support. By the way, with the exception of a few figures of Excel output, software issues are pretty void in this book. And the use of Excel is questionable considering its accuracy problems (well documented).
For blackbelts, my advice is to pick up a management dedicated six-sigma book. Then for technical side, one is best served to arm themselves with authorative references. For ANOVA and DOE, consider Montgomery's "Design of Experiments" book and also consider Neter and Wasserman's "Applied Linear Models". For statistical process control, there is a gem of a book by Alwan titled "Statistical Process Analysis". Alwan's book covers basic SPC but takes process analysis to the next level by covering issues of nonnormality and time-series/SPC using a lot of Minitab (Pyzdek actually references his work). Armed with this collection of these basic references you will be no doubt have the technical skills of a master black belt or actually beyond.
Good luck.reviews: page 1, 2, 3
