Many organizations use Capability Maturity ModelsR (CMMsR) 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 (CMMIR) 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.
