Many talented people were involved in the development of the V1.3 CMMI Product Suite. Three primary groups were the CMMI Steering Group, Product Team, and Configuration Control Board (CCB).

The Steering Group guided and approved the plans of the Product Team, provided consultation on significant CMMI project issues, and ensured involvement from a variety of interested communities.

The Steering Group oversaw the development of the Development constellation recognizing the importance of providing best practices to development organizations.

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 CCB is the official mechanism for controlling changes to CMMI models, appraisal related documents, 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.

Members of the groups involved in developing CMMI-DEV, V1.3 are listed in Appendix C.
