CMMI is an acronym for “Capability Maturity Model Integrated.” The last word basically means that CMMI is a fusion of best practices from a number of different capability maturity models that were eventually combined into a single model that is reminicent of the CMM.

Maturity means that whatever the company is doing, the company does it in a way that is well-documented, where everyone knows what is expected of them and perform accordingly, where performance is not dependent on heroes, and where decisions are made on proper analysis of the situation.
