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
