A very good book, but he seems to be a bit surprised that top management teams doesn't work. Hmmm… let us see: to become a player at the top, you need to be career oriented and have a will to become a top-dog (including playing politics). I wonder why the team approach doesn't work at this level? If we disregard the naivite of a McKinsey director, it is absolutely one of the better books I've read.
