What does a practice group provide within the CMMI model?

A practice group within the CMMI model serves as an organizing structure for practices within a Practice Area. This is crucial because it aligns various practices that share a common objective or focus, enabling organizations to understand and implement those practices more effectively. By categorizing related practices together, a practice group enhances clarity and coherence, making it easier for organizations to adopt and integrate them into their processes. This structured approach also aids organizations in assessing their current capabilities in specific areas and identifying areas for improvement, which is fundamental to the maturity model's goals.

While options like aid for understanding and adoption, a path for performance improvement, and organizing structures for Capability Areas are relevant in the context of CMMI, they do not specifically capture the primary function of a practice group as an organizing framework within Practice Areas.
