In version 2.0 these three areas (that previously had a separate model each) were merged into a single model. 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.
There are Five maturity levels. However, maturity level ratings are awarded for levels 2 through 5. The process areas below and their maturity levels are listed for the CMMI for Development model: Maturity Level 2 - Managed. CM - Configuration Management; MA - Measurement and Analysis; PMC - Project Monitoring and Control; PP - Project Planning
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was formed to sort out the problem of using multiple models for software development processes, thus the CMMI model has superseded the CMM model, though the CMM model continues to be a general theoretical process capability model used in the public domain.

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.
The CMMI Product Team has reviewed more than 1,150 change requests for the models and 850 for the appraisal method. As part of its mission to transition mature technology to the software community, the SEI has transferred CMMI-related products and activities to the CMMI Institute, a 100%-controlled subsidiary of Carnegie Innovations, Carnegie ...
Top level Configuration Management Activity model. Configuration management (CM) is a management process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life.
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 ...
A diagram constructed with meta-modeling to express a process. A process-data diagram consists of two integrated models. The meta-process model on the left-hand side is based on a UML activity diagram, and the meta-data model on the right-hand side is an adapted UML class diagram. Combining these two models, the process-data diagram is used to ...
