“A good book for people who deal with SAP systems for a living. I haven’t read another book like this. It’s technical but it’s also an entertaining read. A pleasant departure from the norm.”
—David C. Gilliland, Senior Consultant, SAP America, Inc.

“Clearly, this book could be used as an excellent development tool and could help a company like mine perfect performance tuning steps and standards.”
—Dennis Prince, SAP Development/Support Specialist, Hewlett-Packard

“SAP optimization is one of those subjects that developers struggle to find time for and managers don’t know is necessary. Presenting the value of the process up front serves to give the developer ammunition to win time for optimization and the manager an education in the value and necessity of optimization. Even if the manager types don’t read past chapter 3, George’s job is done. They should be convinced that someone technical in their IT department needs to be reading this book. Anderson explains the value, then the core technology, and then when we’re all on the same page, the process. To me, that was very helpful.”
—Crew Reynolds, Software Development Manager, Daydots

“This book features good discussion on performance tuning the mySAP suite that no other books have so far. This is the perfect book for SAP Stress Test Project Managers, SAP Stress Test Project Teams, SAP Basis Administrators, Oracle DBAs, Unix Administrators managing SAP systems, and project implementation teams. Those who stress test their systems well with the help of this book will have significant returns.”
—Sanjoy Rath, SAP Consultant
