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 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.
