What signifies a Level 3 maturity in CMMI?

Level 3 maturity in the CMMI framework, often referred to as the "Defined" level, signifies that an organization has established well-defined processes that are standardized across projects and teams. At this level, processes are documented, followed, and supported by structured procedures that provide a clear understanding of how work is to be performed.

This level builds upon the previous levels by not only establishing processes but also ensuring that these processes are tailored from the organization's set of standard processes. It emphasizes consistency and adherence to these documented practices, leading to improved predictability and performance across projects. The focus on having defined processes allows for commonality and reuse, which enhances the organization's ability to deliver quality products and services effectively and efficiently.

Thus, it is the presence of these defined and documented processes that is the hallmark of Level 3 maturity, distinguishing it from lower levels that are characterized by ad-hoc practices, lack of structure, and unpredictability.
