CMMI is an integrated model framework which consists of many capability maturity models that contain the best process and performance practices and was developed by the SEI of Carnegie Mellon University and its well known as an international advanced improvement model for competitive organizations that want to achieve the best performance of operations.
The CMMI has five classifications or levels where each project can be classified into one of these levels where the level is so much progressively hard to achieve and each level builds on to the next level.
To be classified into a CMMI level the process qualifying must meet all the criteria for that level noting that there is a level 0 or incomplete where this level is a representation of the absence or incompleteness of an activity so if we are starting a project we are at least at level 1 of the CMMI.
