What are significant events in a project?

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

Answer: (A)

Milestones are the significant events that mark important points in a project timeline when a phase is completed or a decision is needed. They function as progress checkpoints, helping the team and stakeholders see how the project is advancing and when to review, approve, or move to the next stage. Because milestones signal when meaningful work has been completed or a critical approval has been obtained, they guide planning, communication, and governance.

They aren’t the outputs the project delivers (those are deliverables), nor are they risks (uncertainties that could impact the plan) or constraints (limits on scope, time, or resources). By defining milestones, you create a clear schedule of key moments to aim for, such as kickoff, requirements sign-off, design review, testing phase completion, and final handover.
