Just having done a QM implementation without consultants, I know how much detail there is to wade through. This book would have been invaluable during that time, and has since allowed me to make several enhancements to my implementation. it touches on nearly every aspect of the QM module, and gets fairly in depth in many areas. The process maps from SAP to the ISO/QS standards alone were worth the price of the book. if you are thinking about sap qm, don't do it without this book.
