Interesting title and subject. An easy read, even if I believe that the author is concentrating a bit too much on the financial side (but he manages to touch on Risk Management and Business Cases as well). I can agree with him that the financial side is usually lacking in PMs knowledge, as most of them don't have MBAs (or equivalent), and he manages to present the financial knowledge that is relevant to a PM and can help them in their role in a very nice way.

If you are in PM, this is a book that you definitely should have read. If you have an MBA or are studying to one, there isn't very much that isn't covered elsewhere and in greater detail.

All in all, a very good book.
