This is really a book about focus, which adds some models that are intuitive but not obvious. What is boils down to is that you have to choose between one of the operational excellence, product leadership, or customer intimacy models to excel in. And of course to remember: You can't make money trying to be all things to all people.

This could probably have been written by Al Reis. It is one of the latest fads, and as all fads, fails to give any real methods on how to apply the fad.

Nonetheless, I believe this is a book that should have been read before anyone tries to achieve any higher position.
