When I visited the Amazon page today I noticed that those who bought the first book are already ordering the book on integration. We expected that. Here is some inside story on both the books. We wrote the book on integration while Luke and Amy wrote the second edition of the book titled SuccessFactors with SAP ERP HCM. Luke and I discussed the table of contents of the integration book and ensured that the book on integration complements the book on products and vice versa. In fact, Luke shared the chapter on integration from his book with me and I shared the table of contents of the book on integration and some chapters with Luke to ensure that readers of the books get full value for their money and time investment. The publisher and editors of both books also reviewed the content of both books in details to ensure the same.
The authors of both books are practitioners who write from experience. Each one of them has taken hundreds of hours from their busy schedules last year to generously share their wisdom with everyone. The integration book in particular is full of case studies for many possible scenarios. Get both the books for yourself or your customers. The books will serve your projects and your career for the next several years very well. If you are an SAP SuccessFactors account executive, reading the book and sharing it with your prospect will significantly speed up the decision making process.
