Having implemented more than 10 complete SAP projects myself (as a consultant and later on as a project manager), I rate this book as very helpful. It has an especially practical approach and is very easy to read. Most of all I appreciated the very personal comments about problems commonly occurring and mistakes often done during the projects live-cycle. But also the checklists, summaries and other tools used in projects are very useful and of a high practical value. I can recommend this book to internal and external project managers, key-users, as well as consultants.
