Query: It's not a book, it's a guide reference.

This is a complete description of the Capability Maturity Model for software from SEI/CMU. The big issue of the book, and the model itself, is that it describes widely what has to be done, but no clue of how to do it. This flexibility is very good to one who has been working with the model for so long, but very hard to news fellows to interpret by themselves.
