A project manager is reviewing the change requests for project documents, deliverables, and the project plan. In which project management process does this review belong?

Monitor and Control Project Work focuses on tracking, reviewing, and reporting overall project progress and performance against the plan - it does not formally review or process change requests.

Direct and Manage Project Work is the process of leading and performing the work defined in the project management plan - it generates change requests but does not review or process them.

Close Project or Phase finalizes all activities and formally closes the project or phase - it does not process change requests, which should be resolved before closure.

Perform Integrated Change Control is the process responsible for reviewing all change requests, approving or rejecting them, managing changes to deliverables, project documents, and the project management plan, and communicating the disposition. This process ensures that changes are considered in an integrated fashion, evaluating their impact across all project knowledge areas before approval. It is the single point of authority for formal change management in PMBOK's integrated approach.
