The first third of the book is an overview of the matrix status and the uses for it. Not bad, but not very breath-taking either.

The last two thirds is a lot of 2x2 matrices and a very brief overview of when to use them and how, and some references to other literature. It doesn't really make this a great book…

I love it for the idea of writing such a book was long needed and it has some twisted humour in it to see the standard management consultant fare so exposed.

A decent read, but don't expect too much.
