- **Capability Maturity Model Integration (CMMI)** is a globally recognized framework that helps organizations improve their processes, enhance product quality, and increase overall performance.

- CMMI is structured into Practice Areas, which define specific process capabilities that organizations must implement and manage. These practice areas are grouped into three major categories:

- **Doing**– Focuses on engineering and project execution activities.

- **Managing**– Ensures monitoring, control, and quality assurance.

- **Enabling**– Supports organizational improvement and infrastructure.

- By implementing these practice areas effectively, organizations can achieve process maturity, reduce risks, improve predictability, and deliver high-quality products and services.
