Which term describes significant events that signal progress in a project?

• A. Deliverables
• B. Constraints
• C. Milestones
• D. Assumptions

Answer: (C)

Milestones describe significant events that signal progress in a project. They mark the completion of key phases or authorization points, providing a clear progress signal for stakeholders and triggering governance activities like reviews or sign-offs. Deliverables are the actual outputs produced by the project, whereas constraints are limits on scope, schedule, or resources, and assumptions are beliefs about conditions that affect planning. Because milestones function as progress checkpoints rather than outputs or constraints, they best fit the description.
