An organization runs successfully because of its processes that seamlessly work together. Thus, it is important for each process to work effectively on its own before all of them can function together as one entity. In order to achieve that goal, the Capability Maturity Model Integration (CMMI) was developed. CMMI is a method designed to help organizations improve their processes.
CMMI has a predecessor in the Capability Maturity Model, or CMM. CMM was first developed in 1987, and further developments continued until 1997. Then five years after that, in 2002, in an effort to integrate all existing CMMs, version 1.1 of CMMI was first released. Four years after, in August 2006, version 1.2 followed.
From then on, CMMI has been used for providing a reliable framework for process improvement for various organizations. Its focus is mainly on engineered solutions which is why it is mostly used by organizations focused on computerized systems and software. CMMI provides them with models after which these organizations can pattern their quest to increase efficiency. More specifically, CMI helps them achieve a balance between being able to stay within a budget to maintain profitability and being able to deliver what customers want in terms of quality at an affordable and competitive price.
It is incorrect to think that CMMI is a reflection of reality. CMMI is merely an integration of models, and models are more often than not idealized. CMMI represents an ideal situation that organizations can use as a basis for their processes, but they must also understand that in reality, unexpected issues come up.
