Process area (CMMI)

src: itthots.files.wordpress.com

The Capability Maturity Model Integration (CMMI) defines a Process Area as, "A cluster of related practices in an area that, when implemented collectively, satisfies a set of goals considered important for making improvement in that area." Both CMMI for Development v1.3 and CMMI for Acquisition v1.3 identify 22 process areas, whereas CMMI for Services v1.3 identifies 24 process areas. Many of the process areas are the same in these three models.

Process Area Organization

In CMMI models, the process areas are organized in alphabetical order according to their acronym. However, process areas can be grouped according to maturity levels or process area categories.
