What is one of the primary focuses of Level 4 in the CMMI framework?

Level 4 of the Capability Maturity Model Integration (CMMI) framework centers on the concept of efficiency through quantitative management. At this maturity level, organizations are expected to take a quantitative approach to manage their processes. This means using statistical techniques and performance measurements to understand, control, and improve their processes more effectively.

The emphasis is on establishing a pattern of performance that can be predicted and optimized, which includes the collection of data related to processes and products. Organizations at this level use metrics extensively to identify areas for improvement and to make informed decisions based on quantitative data rather than solely on qualitative insights.

In contrast, the focus of other levels such as Level 2 involves initial processes and project planning, whereas Level 3 introduces defined processes and organizational standards. Level 5, which follows Level 4, deals with continuous process improvement based on quantitative feedback and new ideas. Thus, Level 4 uniquely prioritizes optimizing processes through quantitative management, distinguishing it from the other levels in the CMMI framework.
