Capability Maturity Model

The CMU Capability Maturity Model ( maturity model ) (short- CMM ®) is a maturity model for assessing the quality ( "maturity" ) of the same software process (software development, maintenance, configuration, etc. ) of organizations and identified the actions to improve.

The variants of the CMU CMM ® were added in late 2003 through Capability Maturity Model Integration (short CMMI ® ) to the proliferation of CM models (each development discipline developed its own model ) counter and a uniform, modular and especially general-purpose model to create.

Other popular, based on the original CMU CMM ® models are Spice for maturity assessment and assessment of software processes and COBIT for IT governance processes.

Historical Development

Composition of the model

In the CMM quality is evaluated on a five stages, the quality increases with each stage. Each stage is associated with specific Key Process Areas, which in turn contain objectives and exemplary activities, how these goals can be reached. The steps are:

Demarcation from other standards

In contrast to DIN EN ISO 9001 CMM was developed specifically for the software process and can be used alternatively or in combination at that.

Another standard, among other things, with the assessment of process maturity engaged in software development, the ISO 15504 standard, also known as Spice.
