An interesting book, that fails to live up to its promises, but still leaves you with something worthwhile.

It is too long-winded, with sometimes strange English and self-promoting of the author. Add to this that most of it comes off as common sense, if you have ever been a manager before. And yes, it is definitely geared towards senior managers; to first-liners it is of extremely limited use.

But it manages to discuss interesting concepts and have some compelling short stories, that make you think, so it leaves a pretty good impression anyway.

Shouldn't be the first book on the subject, but may be read by a middle-manager that finds him-/herself recently promoted. Just don't take everything in the book as gospel.
