CMMI (Capability Maturity Model Integration) is a quality model used in the software industry to assess and improve the maturity of development and project management processes.
The CMMI-5 level, also known as the optimization level, is the highest of the five maturity levels of the model and represents excellence in an organization's processes.
At this level, the organization has established a systematic and continuous approach to improving its processes, using quantitative measures to achieve business objectives.
