Many talented people were involved in the development of 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 guided and approved plans of the Product Team, provided consultation on significant CMMI project issues, and ensured involvement from a variety of interested communities.

The Steering Group initiated the development of the Acquisition constellation, recognizing the importance of providing best practices to acquirers. The Steering Group provided guidance for the development of the CMMI-ACQ model and its accompanying training materials.

The Product Team wrote, reviewed, revised, discussed, and agreed on the structure and technical content of the CMMI Product Suite, including the framework, models, training, and appraisal materials. Development activities were based on multiple inputs. These inputs included 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.

The CMMI Configuration Control Board (CCB) is the official mechanism for controlling changes to 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 identified issues and meet criteria for the upcoming release.

The Acquisition Advisory Board acted as the configuration control board for the Acquisition constellation, approving all changes to the Acquisition constellation. Consisting of experts in the field of acquisition, this group ensured the integrity of the constellation using the same review process as the CMMI CCB.

Members of the groups involved in developing CMMI-ACQ, V1.2 are listed in Appendix C.
