Description: The definition of milestones in project management refers to the process of identifying and describing key events that mark progress and significant stages within a project. These milestones are reference points that allow teams to assess their progress and the effectiveness of their efforts. A milestone can be the end of a project phase, the delivery of a product, the approval of a design, or any other event that has a significant impact on project development. Identifying milestones is crucial for planning and monitoring, as it provides a temporal structure that helps teams stay focused and aligned with project objectives. Additionally, milestones facilitate communication among team members and stakeholders, as they offer a clear way to report progress and achievements. In summary, milestones are essential tools in project management that enable better organization, control, and evaluation of the work performed.
