When are milestones typically added to a project plan?

Milestones are significant points or events in a project timeline that indicate important achievements or phases of the project. Adding milestones at relevant intervals during the project is essential because it allows project managers and teams to track progress, assess performance, and make necessary adjustments throughout the project's lifecycle.

By incorporating milestones at various stages, stakeholders can evaluate whether the project is on track and ensure that objectives are being met. This practice facilitates better communication and coordination among team members, as everyone will have defined targets to work towards. It also aids in identifying potential risks or delays early, enabling proactive management and resolution.

Other approaches, such as only adding milestones at the end, would limit the ability to monitor progress and could lead to increased difficulties in managing the project effectively. Additionally, restricting milestone addition to just the start or only in response to issues would not allow for ongoing evaluation and adjustment, which are crucial components of successful project management.
