This document is organized into three main parts:

• Part One-About CMMI for Acquisition
• Part Two-Generic Goals and Generic Practices, and the Process Areas
• Part Three-The Appendices and Glossary

Part One, "About CMMI for Acquisition," consists of five chapters:

• Chapter 1, "Introduction," offers a broad view of CMMI and the Acquisition constellation, concepts of process improvement, the history of models used for process improvement, and different process improvement approaches.
• Chapter 2, "Process Area Components," describes all of the components of the CMMI-ACQ process areas.
• Chapter 3, "Tying It All Together," assembles the model components and explains the concepts of maturity levels and capability levels.
• Chapter 4, "Relationships Among Process Areas," provides insight into the meaning and interactions of the CMMI-ACQ process areas.
• Chapter 5, "Using CMMI Models," describes paths to adoption and the use of CMMI-ACQ for process improvement and benchmarking of practices in an acquisition organization.

Part Two, "Generic Goals and Generic Practices, and the Process Areas," contains all of this CMMI model's required and expected components. It also contains related informative components, including subpractices, notes, examples, and typical work products.

Part Two contains 23 sections. The first section contains the generic goals and practices. The remaining 22 sections each represent one of the CMMI-ACQ process areas.[1]

To make these process areas easy to find, they are organized alphabetically by process area acronym. Each section contains descriptions of goals, best practices, and examples.

Part Three, "The Appendices and Glossary," consists of four sections:

• Appendix A, "References," contains references you can use to locate documented sources of information such as reports, process improvement models, industry standards, and books that are related to CMMI-ACQ.
• Appendix B, "Acronyms," defines the acronyms used in the model.
• Appendix C, "CMMI for Acquisition Project Participants," contains lists of team members and their organizations who participated in the development of CMMI-ACQ, Version 1.2.
• Appendix D, "Glossary," defines many of the terms used in CMMI-ACQ.
