CMMI is a family of best practice collections to support the improvement of development, service and acquisition organistions.


The best practice collections are also called "reference models", because the best practices are used as a reference to compare an organization against. The purpose of CMMI best practice collections is to support improvement of an organization to make it more competitive. The best practices can be used

  • as a common language
  • to evaluate strengths and weaknesses of organization objectively
  • to prioritize improvement actions

The Capability Maturity Model Integration (CMMI) is published by the Software Engineering Institute (SEI) of the Carnegie Mellon University. Despite its name "Software Engineering Institute", die CMMI models are used for all kinds of businesses. Currently there are three CMMI models:

  • CMMI for Development (CMMI-DEV) supports improvements in organizations that develop software, systems and hardware themselves.
  • CMMI for Acquisition (CMMI-ACQ) supports improvements in organizations that acquire software, systems or hardware from third-party vendors.
  • CMMI for Services (CMMI-SVC) supports supports improvements in organizations that deliver services, e.g. healthcare, logistic or consulting organizations.

All CMMI models have the same structure and share common elements, e.g. the process improvement, support or project management processes. The CMMI models are structured into a set of process areas which cover the practices relevant to development, acquisition or service organizations. A Capability Level can be attained for each process area; the Capability Level describes the degree to which the work in the this process area has been established in an organization. CMMI models also have Maturity Levels. The Maturity Levels prescribe a logical sequence for improving processes, they represent a yardstick against which a development organization can be assessed, and they are a recognized award in the industry.
