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engineering (CMMI-SE/SW) are superseded by the title “CMMI for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

ii Preface

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
