I'm reading this book because Rory Sutherland (from Ogilvy in the UK) has blurbed it, and I respect Rory's recommendations on books. It was good because it recognizes businesses are interdependent, like a human body. His grid lays out 9 areas. If you affect one, you affect others, and you have to take this into account when making decisions. The author claims not much is written on this, and he's probably right, though Peter Drucker did talk about it, so does Gary Hamel, Stephen Covey, among others. There's some excellent points in the book, though none of the topics are covered in depth (pricing, for example), but he does include a useful suggested reading list for those who want to dive deeper into a particular area. A worthwhile read.
