Explanation
According to the PMBOK Guide, integrated change control is the process of reviewing all change requests, approving changes, and managing changes to deliverables, organizational process assets, project documents, and the project management plan. The project manager should perform integrated change control to evaluate the impact of the client's request on the project scope, schedule, cost, quality, and risk, and to determine the best course of action to address the change. The project manager should also communicate the change and its implications to the relevant stakeholders, and update the project management plan and other documents accordingly. Performing integrated change control will help the project manager to manage the expectations of the client and the project team, and to ensure the project's alignment with the business objectives.
