I had this as a text book for an organizational leadership class at the master's degree level. The material is repetitive in its chapter presentations, but the core elements are still good. I just didn't find it to be reader-friendly. For some reason the authors feel compelled to remind the reader every few paragraphs that the responses of more than "6,000 team members" form the basis of their conclusions. I understood that point based on the title and didn't need to be reminded on each page. The book reads as if someone went straight to print with their research paper, rather than making it an engaging read. By chapter 3 I no longer cared about the value of the content, I just hated the book. Seriously. You've been warned.
