Change management is the structured process for requesting, evaluating, and approving modifications to project scope, schedule, or cost baselines, not a scheduled phase-end review.

A milestone is a significant, zero-duration point in the project schedule that marks the completion of a major deliverable or phase. Phase-end reviews mandated by the PMO, where quality and budget are formally assessed before the project advances, are designated as milestones because they represent a measurable, planned checkpoint. This type of scheduled review with stakeholder sign-off confirms phase completion and is built into the project timeline as a formal control point.

Incident response is a reactive process for addressing unplanned failures or security events, not a planned, scheduled review with PMO and stakeholders.
