Capability Maturity Model Integration

Capability Maturity Model Integration (CMMI) is a process level improvement training and appraisal program. Administered by the CMMI Institute, a subsidiary of the Information Systems Audit and Control Association (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 process improvement across a project, division, or an entire organization.

CMMI defines five maturity levels (1 to 5) for processes: Initial, Managed, Defined, Quantitatively Managed, and Optimizing. CMMI Version 3.0 was published in 2023; CMMI is registered in the U.S. Patent and Trademark Office by CMU.
