The Capability Maturity Model Integration (CMMI) is a framework and maturity model that is widely used in software development and other areas. It was developed by the Software Engineering Institute (SEI) at Carnegie Mellon University and is used to evaluate and improve the performance and maturity of processes in organizations.
CMMI focuses on the development and maintenance of processes in an organization and provides a structured and hierarchical model composed of different maturity levels. The different maturity levels represent the stages of process maturity and the ability of an organization to manage these processes effectively. There are five maturity levels in the CMMI: Initial, Managed, Defined, Quantitatively Managed, Optimizing.
