When changes to the project scope are identified, it's important for the project manager to review these changes with the project stakeholders. This allows for a collective understanding of the impact of the scope reduction on the project's objectives, deliverables, and schedule. It also ensures that all stakeholders are aligned and in agreement with the proposed changes. This approach is in line with the PMBOKGuide's emphasis on integrated change control, which involves reviewing all change requests, approving changes, and managing changes to deliverables, organizational process assets, project documents, and the project management plan.
