This is a nice little book. Chetan is a systems thinker and he uses this technique to analyse the behaviour of bosses. I'm pretty familiar with this way of thinking and the worldview that goes with it, but possibly someone who is new to it would take more convincing of Chetan's argument.
The conclusion of the book is that to change managers' behaviour you need to change the way they are appointed. Sadly this is unlikely to start happening any time soon where I work, so it leaves me a little depressed to think that there is nothing I can do about it, other than leave.
Thinking about the boss problem, a cause is the ownership structure. Not only, as Chetan says, are all the bosses afraid of their bosses, the CEO is afraid of stock market analysts - maybe this is an idea Chetan could explore further.
Chetan is not able to propose easy fixes, because the causes run deep, but perhaps this book will be the beginning of a movement.
The book is an easy read and entertaining with a good selection of anecdotes & stories to illustrate his points.
