CMMI was developed by a group from industry, government, and the Software Engineering Institute (SEI) at CMU. CMMI models provide guidance for developing or improving processes that meet the business goals of an organization. A CMMI model may also be used as a framework for appraising the process maturity of the organization. [3]
The full representation of the Capability Maturity Model as a set of defined process areas and practices at each of the five maturity levels was initiated in 1991, with Version 1.1 being published in July 1993. [3] The CMM was published as a book [4] in 1994 by the same authors Mark C. Paulk, Charles V. Weber, Bill Curtis, and Mary Beth Chrissis.
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.
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 ...
ISO/IEC 15504 is the reference model for the maturity models (consisting of capability levels which in turn consist of the process attributes and further consist of generic practices) against which the assessors can place the evidence that they collect during their assessment, so that the assessors can give an overall determination of the organization's capabilities for delivering products ...
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
Automotive SPICE is a maturity model adapted for the automotive industry. It assesses the maturity of development processes for electronic and software-based systems (e.g., ECUs).
CMMI Version 1.3 was released on November 1, 2010. This release is noteworthy because it updates all three CMMI models (CMMI for Development, CMMI for Services, and CMMI for Acquisition) to make them consistent and to improve their high-maturity practices. The CMMI Product Team has reviewed more than 1,150 change requests for the models and 850 ...
