CMMI - Level 4 - Quantitatively Managed

Level 4 - in CMMI is a very critical step.

At this level, the organization has achieved all the goals of PAs in Level 2, 3 and 4.

They key attribute of Level 4 is sub process performance. The selected sub processes are controlled using statistical and other quantitative techniques

At Level 4, process and project management happens through Quantitative techniques. Quantitative objectives are based on the needs of the client, end users, organization and process improvement. Quality and process performances are understood in statistical terms and are managed throughout the life of the processes.

For the various processes, measures of process performance are collected and statistically analyzed. Special Causes of process performance are identified and corrected to prevent future occurrences.

The crucial difference between Level 3 and 4 is Predictability.

At Level 4, performance of process is quantitatively predictable.

There are 2 PAs at this level:

1. Organizational Process Performance (OPP)
2. Quantitative Project Management (QPM)


Next - CMMI - L4 - Quantitatively Managed - OPP, QPM
