I bought this book to prepare for the ASQ CQE exam. This was my primary reference book and I did pass the exam - so there must be some merit to this book. However, it is frustrating. My criticisms include:
- the index doesn't point to the right pages, making it very difficult to use (especially in an open book exam)
- some of the graphs have no labelling at all (Fig IV.28)
- some material is repeated (eg central limit theorem)
This book has some good stuff in it and is aimed at getting you through the CQE exam. It will also be useful for a practicing quality engineer. However, it is in many cases separate articles, procedures and discussions stuck together with little flow. A good review and editing would do a lot for this book.
