Quatrième de couverture
Many organizations use Capability Maturity Models® (CMMs®) to assess development and maintenance processes, implement improvements, and measure progress. Although consistent in purpose, these models differ in terminology and design--enough sometimes to cause conflict and confusion when used within the same organization. Addressing the need for a more coordinated approach, Capability Maturity Model Integration (CMMI®) provides a single framework for improvement in software engineering, systems engineering, integrated product and process development, and supplier sourcing.
This book is the definitive reference for the most current release of CMMI models. To use a CMMI model available on the SEI Web site, users must choose from among multiple models based on their organization's improvement needs. This book provides a single source for all CMMI model information. Readers can get started without having to select a model first--all of the choices are compiled in one place and explained in detail.
The book begins with background information needed to understand the content and structure of these integrated models and how to use them. A case study illustrates their implementation in a real environment. A variety of practical material, such as glossary and index, is also provided. The bulk of the book comprises the content of all CMMI models, covering the 25 process areas (PAs) that span the product life cycle, including detailed best practices.
All CMMI models have two representations. The continuous representation allows an organization to improve using selected PAs at different rates. The staged representation enables organizations to follow a predefined and proven improvement path using multiple PAs. Both representations are described so that readers will more clearly see the similarities and differences between the two representations and will be able to choose the right approach for their organization.
Whether you are new to CMMI or are already familiar with some version of it, this book is an essential resource for managers, practitioners, and process improvement team members who need to understand, evaluate, and/or implement a CMMI model. The ultimate objective of CMMI is integrating processes to improve products; this book contains everything you need to get that done.

This book answers those questions and more, explaining in pretty practical language what the CMMi is, what the structure of the whole model is about, and finally tunneling down into the details of each process area. I wish I had that knowledge when we were making some of our initial decisions.
I'm not exactly a fan of the CMM/CMMi methodologies, but I have experienced first hand the result of the improvement efforts we have introduced. Ultimately though, I don't think it matters much WHAT methodology you are following; a group of people interested in improving themselves will do well with any methodology, CMMi, RUP, Agile, or otherwise. If you are committed to the CMMi approach, this book needs to be in your toolchest. If you are evaluating different process improvement efforts, this book will help you understand the CMMi approach. It doesn't provide any comparison or contrast to other methodologies; for that you would need other reference material.
process area description.
- 33 pages consist of a case study of a CMMI implementation.
- 70 pages are references, glossary and index.
- the remainging 100 pages are a re-hash of general
CMMI information plus -more importantly- additional
information on the interpretation of generic goals and
on process areas relationships revealing that around
15 process areas are "fundamental" and the rest is
"progressive". my interpretation of "fundamental" is
"you need them really".
overall it would have been more precise if the title would
read "CMMI 1.1 annotated reference".
re-reading parts of the book i have to further downgrade it:
1. in the preface section it gives the misleading advice that
the CMMI can be used for service industries and that it covers
the whole product life cycle. this is not true: the CMMI is a
standard for development only.
2. the book further claims that the CMMI is the best model
for process improvement. there is no evidence i am aware of
that supports this claim.
3. the book recommends to use the staged representation
of the CMMI in case of uncertainty. this is a highly doubtful
advice considering the fact the the PA sequence of the stage
representation has major disadvantages.
Reasons to buy this book instead of obtaining the 'official documentation' from SEI (see ASIN B0000Y4PCA)include:
- Better organized. Finding specific information among the documents you can obtain from SEI can sometimes be a daunting task. Yes, it's complete, but there are multiple documents, and this book has distilled and organized all of the pertinent information between two covers.
- Case studies in this book add life to the material, and the overall writing style of all of the material in this book is more readable. The SEI document set includes some well-written material to be sure, but there is also dense text that is a chore to wade through from a readability standpoint.
For understanding the CMMI this book is one of the best, in my opinion. It gives the evolution of the CMMI from the earlier CMM models, discusses key benefits, and goes into details. However, if you already understand the CMMI, and are seeking information for implementation I recommend "Interpreting the CMMI: A Process Improvement Approach" (ISBN 0849316545). That book outlines how to implement the CMMI and provides a wealth of supporting material.
The rest of the book, some 450 pages, covers the integral details of the individual process areas, as well as the specific and generic goals and practices to fully implement the model. It can be information overload at first for the neophyte process engineer. However, once one is acclimated to the processes this manual will serve as a ready technical bible for guidance through the Process Improvement morass using CMMI.
Be advised though that nowhere in the CMMI, nor in this manual, is there any specific implementation instructions on how to actually execute an activity. For that one should look to the IEEE or ITIL libraries for templates and examples. Alternatively, if you are serious about CMMI and your goal is to achieve successful SCAMPI assessments; finding/hiring an experienced process engineer or consulting company to lead you or your team through this exercise is highly recommended.
