I thought this was a frustrating read. After a principle is introduced, there's a case study of an unnamed executive at an unnamed company and then each chapter ends with a call to action to visit the author's consulting company website. The chapters are long on _what_ but short on _how_. It was all very frustrating.
Then, in the last chapter, it all came together. He ties it all together into a single coherent framework that is immediately actionable. The last chapter makes all those that came before worth it.
In the end, if you're willing to work for it, this is actually a pretty good book.
