The first half of this book is an interesting history of McKinsey and the management consulting business as a whole, from its humble beginnings, and as such pretty good.

The second half feels more like name-dropping and opinions on how McKinsey developed through various stages, and even that is not really set inside any wider perspective or analysed in any depth.

A decent book, but it could have been a lot shorter. Interesting if you want to know how McKinsey and the managing consulting business started, but don't expect any insights on how they work today.
