When the first edition of this book was published in 2001, CMMI (Capability Maturity Model Integration) was largely viewed as a standard that was "on the horizon." In the past two years, CMMI has -- pardon the pun -- matured greatly. CMMI is now a recognized and widely-adopted model. This new edition reflects CMMI version 1.1 (the first edition was based on version 1.0). The book contains expanded coverage on the realized return on investment that can be attained through process improvement with CMMI, and the pioneer case studies have been replaced with broader CMMI-specific experience that will enable the reader to more easily adopt this model. The authors also share their understanding of how the CMMI will continue to adapt and remain relevant for years to come. The result is a handy book that is informative, useful, and appropriate to the reader's needs.
This book is useful to those who are fairly well-versed in CMMI. For me, this is by far the best "reference" material, since it is concise, and it consolidates separate points into a table or a 1-pager with diagrams, making it easier to digest and understand. This is especially so when compared with the thick (700+ pages) big (A4 size) tome official guidebook from SEI. I could easily take Ahern onto the plane / train for quick brush-up on particular process areas. I would recommend this book to those who had already gained some CMMI knowledge, and would need a light handbook for quick reference.
