According to the PMBOK Guide, the review of change requests, deliverables, and the project management plan occurs within the Monitor and Control Project Work process. This process is concerned with tracking, reviewing, and reporting the overall progress to meet the performance objectives defined in the project management plan.
* Reviewing Change Requests: During this process, the project manager monitors the status of change requests and ensures that only approved changes are implemented.
* Reviewing Deliverables: The project manager compares actual project performance (deliverables produced) against the project management plan to see if any variances exist.
* Context within Integration Management: This process provides the project management team with insight into the health of the project and identifies any areas requiring special attention. It is the " big picture " monitoring process that looks across all knowledge areas.
Why other options are incorrect:
* Direct and Manage Project Work (Option B): This is the Executing process where the work is actually performed and deliverables are created. While it involves " Work Performance Data, " the high-level review against the plan happens in Monitoring and Controlling.
* Close Project or Phase (Option C): This process happens at the end of a project or phase. While it involves a final review of deliverables, it does not focus on the ongoing monitoring of change requests and plan performance throughout the project lifecycle.
* Perform Integrated Change Control (Option D): This process is specifically focused on approving or rejecting change requests. While it involves reviewing change requests, it does not encompass the broad review of all project deliverables and overall plan performance that characterizes " Monitor and Control Project Work. "
