Capability Maturity Model Integration (CMMI) is a process level improvement training and appraisal program. Administered by the CMMI Institute, a subsidiary of ISACA, it was developed at Carnegie Mellon University (CMU). It is required by many U.S. Government contracts, especially in software development. CMU claims CMMI can be used to guide ...
The suite of documents associated with a particular version of the CMMI includes a requirements specification called the Appraisal Requirements for CMMI (ARC), [2] which specifies three levels of formality for appraisals: Class A, B, and C. Formal (Class A) SCAMPIs are conducted by SEI-authorized Lead Appraisers who use the SCAMPI A Method Definition Document (MDD) [3] to conduct the appraisals.
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: CMMI for Acquisition ; CMMI for Development ; CMMI for Services
The Capability Maturity Model Integration (CMMI) project was formed to sort out the problem of using multiple models for software development processes, thus the CMMI model has superseded the CMM model, though the CMM model continues to be a general theoretical process capability model used in the public domain. [16] [citation needed] [17]
The implementation maturity model (IMM) is an instrument to help an organization in assessing and determining the degree of maturity of its implementation processes. This model consists of two important components, namely the: five maturity levels, adopted from capability maturity model (CMM) of the Software Engineering Institute (SEI).
Experience has indicated that many organizations initiate the formal development of workgroups while working toward Maturity Level 3. Thus, Version 2 of the People CMM initiates process-driven workgroup development at Maturity Level 3. This change is consistent with the placement of integrated teaming activities at Maturity Level 3 of the CMMI ...
A maturity model is a framework for measuring an organization's maturity, or that of a business function within an organization, [1] with maturity being defined as a measurement of the ability of an organization for continuous improvement in a particular discipline (as defined in O-ISM3 [dubious – discuss]). [2]
CMMI for Development was the first of three constellations defined in Version 1.2: the others include CMMI for Acquisition and CMMI for Services. The CMMI for Services constellation was released in February 2009. Another management practice developed by CERT, which is part of the SEI, is the Resilience Management Model (CERT-RMM).
