I think this is a pretty good book on strategy, I have read a few and it ranks up there with the best.
The only reservation that I have is that it is very high level. I know that that is the angle it's being sold at but I feel that there are distinctive advantages to covering more bases.
If you are an account manager, business owner or CEO, yes this is probably for you. If not and this is your first foray into such a book might I suggest you start a little lower down the tree in order to learn more faster ;)
