CMMI for Development Version 1.2 Preface i Preface CMMI ® (Capability Maturity Model ® Integration) is a process improvement maturity model for the development of products and services. It consists of best practices that address development and maintenance activities that cover the product lifecycle from conception through delivery and maintenance. This latest iteration of the model as represented herein integrates bodies of knowledge that are essential for development and maintenance, but that have been addressed separately in the past, such as software engineering, systems engineering, hardware and design engineering, the engineering “-ilities,” and acquisition. The prior designations of CMMI for systems engineering and software engineering (CMMI-SE/SW) are superseded by the title “CMMI for Development” to truly reflect the comprehensive integration of these bodies of knowledge and the application of the model within the organization. CMMI for Development (CMMI-DEV) provides a comprehensive integrated solution for development and maintenance activities applied to products and services. CMMI for Development, Version 1.2 is a continuation and update of CMMI version 1.1 and has been facilitated by the concept of CMMI “constellations” wherein a set of core components can be augmented by additional material to provide application-specific models with highly common content. CMMI-DEV is the first of such constellations and represents the development area of interest. Purpose The purpose of CMMI for Development is to help organizations improve their development and maintenance processes for both products and services. CMMI for Development is a collection of best practices that is generated from the CMMI Framework. 1 The CMMI Framework supports the CMMI Product Suite by allowing multiple models, training courses, and appraisal methods to be generated that support specific areas of interest. 1 The CMMI Framework is the basic structure that organizes CMMI components and combines them into CMMI constellations and models. CMMI for Development Version 1.2 Preface ii A constellation is a collection of CMMI components that includes a model, its training materials, and appraisal-related documents for an area of interest. Currently there are three planned constellations supported by the version 1.2 model framework: development, services, and acquisition. “Additions” are used to expand constellations for specific additional content. This document contains the CMMI for Development constellation and contains both the base CMMI-DEV as well as CMMI-DEV with the IPPD addition (CMMI-DEV+IPPD). If you are not using IPPD, ignore the information that is marked “IPPD Addition,” and you will be using the CMMI for Development model. Unlike CMMI version 1.1, there is but a single model document that describes both the staged and continuous approaches to process improvement versus the prior use of two representations of staged and continuous in separate documents. This consolidated presentation of model material for both approaches was first used in the book, CMMI: Guidelines for Process Integration and Product Improvement. Thanks to Peter Gordon, publishing partner at Addison-Wesley Professional, and the book’s authors, Mary Beth Chrissis, Mike Konrad, and Sandy Shrum, we were able to use the book’s manuscript as the basis for developing CMMI version 1.2 [Chrissis 2003]. Acknowledgments Many talented people were involved as part of the product team for the CMMI v1.2 Product Suite. Three primary groups involved in this development were the Steering Group, Product Team, and Configuration Control Board. The Steering Group guides and approves the plans of the Product Team, provides consultation on significant CMMI project issues, and ensures involvement from a variety of interested communities. The Product Team writes, reviews, revises, discusses, and agrees on the structure and technical content of the CMMI Product Suite, including the framework, models, training, and appraisal materials. Development activities are based on multiple inputs. These inputs include an A- Specification and guidance specific to each release provided by the Steering Group, source models, change requests received from the user community, and input received from pilots and other stakeholders [SEI 2004]. The Configuration Control Board is the official mechanism for controlling changes to the CMMI models and Introduction to CMMI training. As such, this group ensures integrity over the life of the product suite by CMMI for Development Version 1.2 Preface iii reviewing all proposed changes to the baseline and approving only those changes that satisfy the identified issues and meet the criteria for the upcoming release. Members of these groups that were involved in developing CMMI v1.2, are listed in Appendix C. Audience The audience for this model includes anyone interested in process improvement in a development and maintenance environment. Whether you are familiar with the concept of Capability Maturity Models or whether you are seeking information to get started on your improvement efforts, this document will be useful to you. This model is also intended for people who want to use an appraisal 2 to see where they are, those who already know what they want to improve, and those who are just getting started and want to develop a general understanding of the CMMI for Development constellation. Organization of This Document This document is available on the SEI Web site 3 and serves as a guide for improvement of organizational processes. It is organized into three main parts: • Part One—About CMMI for Development • Part Two—Generic Goals and Generic Practices, and the Process Areas • Part Three—The Appendices and Glossary Part One, “About CMMI for Development,” consists of five chapters: • Chapter 1, “Introduction,” offers a broad view of CMMI and the CMMI for Development constellation. It introduces you to the concepts of process improvement, and describes 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 for Development process areas. 2 An appraisal is an examination of one or more processes by a trained team of professionals using a reference model (e.g., CMMI) as the basis for determining strengths and weaknesses. 3 The SEI Web site is located at http://www.sei.cmu.edu. CMMI for Development Version 1.2 Preface iv • 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 for Development process areas. • Chapter 5, “Using CMMI Models,” describes paths to adoption and use of CMMI for process improvement and benchmarking. Part Two, “Generic Goals and Generic Practices, and the Process Areas,” contains all of the CMMI for Development constellation’s required and expected components. It also contains related informative components, including component names, subpractices, notes, and typical work products. Part Two contains 23 sections. The first section contains the generic goals and practices, including a description of how they are used and how they relate to the process areas. The remaining 22 sections each represent one of the CMMI for Development process areas. 4 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 information resources: • 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 for Development. • Appendix B, “Acronyms,” defines the acronyms used herein. • Appendix C, “CMMI for Development Project Participants,” contains lists of people and their organizations who participated in the development of CMMI for Development, Version 1.2. • The “Glossary” defines many of the terms used in CMMI. How to Use This Document Whether you are new to process improvement, new to CMMI, or already familiar with CMMI, Part One can help you understand why CMMI for Development is the best model to use for improving your development and maintenance processes. 4 A “process area” is a cluster of related best practices in an area, which when implemented collectively, satisfy a set of goals considered important for making significant improvement in that area. We will cover this concept in detail in Chapter 2. CMMI for Development Version 1.2 Preface v Readers New to Process Improvement If you are new to process improvement or new to the CMM ® concept, we suggest that you read Chapter 1, “Introduction,” first. Chapter 1 will give you an overview of process improvement and explain what CMMI is all about. Next, skim Part Two, including generic goals and practices as well as specific goals and practices, to get a feel for the scope of the best practices contained in the model. Pay closest attention to the purpose and introductory notes at the beginning of each section. In Part Three, look through the references in Appendix A and select additional sources you think would be beneficial to read before moving forward with using CMMI for Development. Read through the acronyms and glossary to become familiar with the language of CMMI. Then, go back and read the details of Part Two. Readers Experienced with Process Improvement If you are new to CMMI but have experience with other process improvement models, such as the Software CMM (version 1.1) or the Systems Engineering Capability Model (i.e., EIA 731), you will immediately recognize many similarities [EIA 1998]. We recommend that you read Part One to understand how CMMI is different from other process improvement models, but you may want to read some of the sections more quickly than others. Read Part Two with an eye open for best practices you recognize from the models you have already tried. Identifying familiar material gives you a feel for what is new and what has been carried over from the model you already know. Next, review the glossary to understand how some terminology may differ from that used in the process improvement model you know. Many concepts will be repeated, but they may be called something different. Readers Familiar with CMMI If you have reviewed or used a CMMI model before, you will quickly recognize the CMMI concepts discussed and the best practices presented. The differences between version 1.2 and version 1.1 are explained in detail on the SEI Web site in the version 1.2 release notes. These differences reflect the enhancements suggested by the users of version 1.1. CMMI for Development Version 1.2 Preface vi The following improvements were made to version 1.2: • Both representations are presented together. • The advanced practice and common feature concepts have been removed. • The generic goal and practice descriptions were moved to Part Two. • Hardware amplifications were added. • All definitions were consolidated in the glossary. • IPPD practices were consolidated and simplified. There are no longer any separate IPPD process areas. • Supplier Agreement Management (SAM) and Integrated Supplier Management (ISM) were consolidated and Supplier Sourcing was removed. • Generic practice (GP) elaborations were added to the level 3 GPs. • An explanation of how process areas support the implementation of GPs was added. • Material was added to ensure that standard processes are deployed to projects at their startup.
