What does entering a duration entail when creating a milestone?

When creating a milestone in project management, entering a duration primarily involves establishing a time frame that must be met. Milestones serve as significant checkpoints or goals within a project, helping to gauge progress and ensure that the project is on track. In this context, defining a duration means identifying the specific deadline by which a certain outcome or deliverable must be achieved.

While some may think that defining the length of the milestone refers to the duration, it's important to note that milestones, by their nature, do not have a length in terms of days or hours. Instead, they represent a point in time. Thus, the focus is more on the timeframe for achieving the milestone rather than the duration itself. The other options, such as assigning resources or calculating project costs, are related to project management but do not specifically pertain to what entering a duration for a milestone signifies.
