What is a change request and what happens when one is submitted?

A change request is a formal proposal to modify any document, deliverable, or baseline. It can be corrective action to realign performance with the plan, preventive action to reduce the probability of negative consequences, defect repair to fix a nonconforming deliverable, or a scope change adding or removing work. When submitted, the change request is logged, the project manager assesses its impact across all knowledge areas, the Change Control Board reviews and approves or rejects it, and if approved, the project management plan and baselines are updated accordingly.
