Which CMMI maturity level focuses on ensuring that everyone follows established procedures and processes?

The Defined maturity level, which is Level 3 in the CMMI framework, emphasizes standardization and organization of processes within an organization. At this level, the focus is on establishing and following documented processes that are tailored from the organization's set of standard processes. This involves ensuring that all team members and stakeholders consistently adhere to these established procedures, leading to greater predictability and efficiency in project execution.

Achieving Defined status means that not only are processes in place, but they are also understood and utilized consistently across the organization. This is crucial for developing a mature approach to process management, where the goal is to achieve repeatable and measurable outcomes by relying on standardized practices. As organizations proceed through the CMMI maturity levels, the importance of disciplined adherence to defined processes becomes pivotal in driving continuous improvement and enhancing performance.
