This is something as odd as how to purchase professional services, written for the purchasing department and senior management of the buying company. Admittedly, it has a certain Anglo-feel, but I believe it may be useful in other parts of the world as well.

With that said, I think even seasoned consultants can get some value by reading this, as it is so broad and may even give some ideas on how to approach customers.

All in all, there is nothing revolutionary in the book, but it has its values.
