What is integrated change control and who approves changes?

Integrated change control is the process of reviewing all change requests, approving or rejecting changes, and managing changes to deliverables, project documents, and the project management plan. All change requests must be formally documented and evaluated for their impact on scope, schedule, cost, quality, and risk before approval. The Change Control Board, or CCB, is the group authorized to approve or reject changes. The project manager facilitates the change control process but does not unilaterally approve changes that affect baselines.
