Who has the MOST control over project scope changes?

Key stakeholders influence changes and are impacted by them, but they typically do not have the sole or final authority to approve all changes.

The project sponsor provides overall project funding and high-level direction, but day-to-day or formal approval of all scope changes is usually delegated to a CCB.

The project manager manages the change process and presents changes to the CCB, but does not typically have unilateral authority to approve all scope changes, especially significant ones.

A Change Control Board (CCB) is a formal group responsible for reviewing, evaluating, approving, delaying, or rejecting changes to a project's baselines, including scope. The CCB ensures that all requested changes are properly documented, analyzed for their impact, and formally decided upon, thus having the most control over scope changes.
