==History==

CMMI was developed by the CMMI project, which aimed to improve the usability of maturity models by integrating many different models into one framework. The project consisted of members of industry, government and the Carnegie Mellon Software Engineering Institute (SEI). The main sponsors included the Office of the Secretary of Defense ([[Office of the Secretary of Defense|OSD]]) and the [[National Defense Industrial Association]].

CMMI is the successor of the [[capability maturity model]] (CMM) or Software CMM. The CMM was developed from 1987 until 1997. In 2002, version 1.1 was released, version 1.2 followed in August 2006, and version 1.3 in November 2010.

In version 2.0 the above representation separation was cancelled and there is now only one cohesive model.

===Model framework (v1.3)===

Line 128:

In version 2.0 DEV, ACQ and SVC were merged into a single model where each process area potentially has a specific reference to one or more of these three aspects. Trying to keep up with the industry the model also has explicit reference to agile aspects in some process areas.

Some key differences between v1.3 and v2.0 models are given below; this is not an exhaustive list. Additional information is available [https://www.cmmiinstitute.com/getattachment/5e9800b1-3637-4da1-bda3-677b8f66e064/attachment.aspx here]

# "Process Areas" have been replaced with "Practice Areas (PA's)". The latter is arranged by levels, not "Specific Goals".
