Which maturity level in CMMI emphasizes stability of processes?

The maturity level in CMMI that emphasizes stability of processes is the Managed level. At this stage, organizations focus on ensuring their processes are planned, performed, measured, and controlled. This level establishes a foundation where processes are more predictable and consistent, which is essential for achieving stability. The Managed level requires organizations to establish basic project management practices that result in controlled and repeatable processes.

Organizations at this level invest in understanding their processes and start to collect data that can provide insights into their performance, thereby fostering a more controlled environment. The goal is to provide reliability in outcomes, leading to a stable operational framework.

As organizations move beyond the Managed level to Defined and subsequently to higher maturity levels like Quantitatively Managed and Optimizing, the focus shifts towards refining processes and using quantitative data to manage them effectively, thus building on the foundational stability of the Managed level.
