Process area (CMMI)

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.

Maturity Levels: CMMI for Development

There are Five maturity levels. However, maturity level ratings are awarded for levels 2 through 5. The process areas below and their maturity levels are listed for the CMMI for Development model:

Maturity Level 2 - Managed

Maturity Level 3 - Defined

Maturity Level 4 - Quantitatively Managed

Maturity Level 5 - Optimizing

Maturity Levels: CMMI for Services

The process areas below and their maturity levels are listed for the CMMI for Services model:

Maturity Level 2 - Managed

Maturity Level 3 - Defined (this includes the process areas that make up the previous levels; Maturity Level 3 is made up of the process areas in Level 2 and Level 3)

Maturity Level 4 - Quantitatively Managed

Maturity Level 5 - Optimizing

Maturity Levels: CMMI for Acquisition

The process areas below and their maturity levels are listed for the CMMI for Acquisition model:

Maturity Level 2 - Managed

Maturity Level 3 - Defined

Maturity Level 4 - Quantitatively Managed

Maturity Level 5 - Optimizing

Goals and Practices

There are two categories of goals and practices: generic and specific. Specific goals and practices are specific to a process area. Generic goals and practices are a part of every process area. A process area is satisfied when organizational processes cover all of the generic and specific goals and practices for that process area.

Generic Goals and Practices

Generic goals and practices are a part of every process area.

Specific Goals and Practices

Each process area is defined by a set of goals and practices. These goals and practices appear only in that process area.

Process Areas

CMMI for Development, Version 1.2 contains 22 process areas indicating the aspects of product and service development that are to be covered by organizational processes. For a summary of process areas for each model, see these quick reference documents available on the SEI website:
