Which Practice Area relates to senior management reviewing the status of the process improvement action plan quarterly?

The practice area that pertains to senior management reviewing the status of the process improvement action plan on a quarterly basis is governance. Governance in the context of CMMI refers to the frameworks, policies, and activities that ensure the organization’s processes are aligned with its strategic objectives. This includes oversight by senior management to assess the effectiveness of process improvement initiatives, ensuring that they are progressing as intended.

Reviewing the status of an action plan is critical in governance as it enables leaders to make informed decisions, allocate resources effectively, and adjust strategies as necessary to achieve organizational goals. This oversight helps establish accountability and provides a structured approach to managing improvements across different processes.

In contrast, the other practice areas focus on different aspects of process management such as the infrastructure needed for implementation, the assurance of quality within processes, and the measurement of performance. While these areas contribute to overall process improvement, they do not specifically address the senior management's role in overseeing and assessing improvement plans on a regular basis, which is a key function within governance.
