||This article contains content that is written like an advertisement. (April 2012)|
- Product and service development (CMMI for Development )
- Service establishment, management, and delivery (CMMI for Services )
- Product and service acquisition (CMMI for Acquisition )
CMMI Version 1.3 was released on November 1, 2010. This release is noteworthy because it updates all three CMMI models (CMMI for Development, CMMI for Services, and CMMI for Acquisition) to make them consistent and to improve their high maturity practices. The CMMI Product Team has reviewed more than 1,150 change requests for the models and 850 for the appraisal method.
Agile Support in CMMI
One major change in CMMI V1.3 is the addition of agile support. Earlier, the SEI published the technical report CMMI or Agile: Why Not Embrace Both, to make clear that CMMI and agile can co-exist. In CMMI V1.3, agile  has been included with an interpretation guideline and by adding notes to the applicable process areas in the introduction of the process area and on how to interpret agile practices.
[clarification needed Some explanation of “constellation” is needed, here and below. N.B. This is used here like CMMI jargon, but is not defined in the main article] Version 1.2 of CMMI models were released in recent years. CMMI for Development was released in August 2006, CMMI for Acquisition was released in November 2007, and CMMI for Services was released in February 2009. Because of the time in between these releases, they have become inconsistent. The work done for Version 1.3 ensures the consistency of these models.
High Maturity Clarifications
The CMMI Product Development Team has formed a High Maturity Team. This team’s members are focusing on improvements to high maturity practices  in all three CMMI models to ensure that they are representative of current best practices in the community. This team’s work focuses on the four high maturity process areas: Organizational Process Performance (OPP), Quantitative Project Management (QPM), Causal Analysis and Resolution (CAR), and Organizational Innovation and Deployment (OID) - CMMI V1.2 / Organizational Performance Management(OPM) - CMMI V1.3.
A number of change requests have suggested further expansion of CMMI models in new directions. Although this release is not suitable for major expansions such as those in the two most recently released constellations, information was added on customer satisfaction, software architecture, and Agile Methods.
Many students taking either of the one-day supplement courses that cover acquisition or service delivery have commented that many organizations span more than one area of interest. One theme for the V1.3 release is to enable sharing of best practices across the constellations. The SCAMPI Method Definition Document is being improved to facilitate appraisals that use process areas from multiple constellations.
