The Capability Maturity Model (CMM) is a way to develop and refine an organization's software development process. A maturity model is a structured collection of elements that describe characteristics of effective processes. A maturity model provides:

  • a place to start
  • the benefit of a community?s prior experiences
  • a common language and a shared vision
  • a framework for prioritizing actions
  • a way to define what improvement means for your organization

A maturity model can be used as a benchmark for assessing different organizations for equivalent comparison.

The SEI has subsequently released a revised version known as the Capability Maturity Model Integration (CMMI).

Capability Maturity Model? Integration (CMMI) is a process improvement approach that provides organizations with the essential elements of effective processes. It can be used to guide process improvement across a project, a division, or an entire organization. CMMI helps integrate traditionally separate organizational functions, set process improvement goals and priorities, provide guidance for quality processes, and provide a point of reference for appraising current processes.

Benefits of CMMI

  • more explicitly link management and engineering activities to their business objectives
  • expand the scope of and visibility into the product life cycle and engineering activities to ensure that the product or service meets customer expectations
  • incorporate lessons learned from additional areas of best practice (e.g., measurement, risk management, and supplier management)
  • implement more robust high-maturity practices
  • address additional organizational functions critical to their products and services
  • more fully comply with relevant ISO standards

CMMI-is a process improvement approach that provides organizations with the essential elements of effective processes.

CMM->software Engineering organizations
CMMI->System Engineering & Software Engineering  organizations

CMM address separately to the fields like engineering, people and software while CMMI integrates these fields and hence can be applied even to manufacturing industry also. In CMM previously we had a process area for organizational environment, which is removed in CMMi. Some of the best practices of various fields mentioned above are integrated in the CMMi.
