Which of the following processes reviews all requests for changes or modifications to project documents, deliverables, baselines, or the project management plan and approves or rejects the changes?

The process that reviews all requests for changes or modifications to project documents, deliverables, baselines, or the project management plan is known as Perform Integrated Change Control. This process is vital in project management as it ensures that changes are carefully considered and evaluated before approval or rejection.

Perform Integrated Change Control involves a structured approach to managing changes; it provides clear guidance on how changes will be assessed for their impact on the project's overall goals, including time, cost, and quality. By having a formal process in place, the project manager and project team can maintain control over project adjustments, aligning them with stakeholder expectations and the project's objectives.

This process also fosters communication among stakeholders, as it typically involves various stakeholders in the evaluation of change requests to navigate their potential effects effectively. Effective change management is critical because even small modifications can have significant implications for a project, making this process an essential component of successful project management.
