Show answer & explanation
Correct answer: A milestone represents a significant point or event in the project with zero duration, while task duration is the time required to complete a specific activity
Explanation
A milestone is a significant point or event in the project timeline that has zero duration—it marks the completion of a major deliverable or phase. Task duration, in contrast, is the actual time period required to complete a specific work activity or task.
**Why not A:** A milestone is not always the first task in a phase — it can occur at any significant point, including phase completion, deliverable acceptance, or key decision points. Milestones are not tasks at all; they are zero-duration markers that signify important events.
**Why not C:** Milestones and task durations are used in both predictive and agile projects. Agile projects use milestones to mark sprint goals or release dates, and predictive projects use task durations for scheduling. Neither concept is exclusive to one methodology.
**Why not D:** Milestones and task durations are fundamentally different concepts and are not interchangeable. A milestone marks a point in time with zero duration, while a task duration measures the time needed to complete work. Confusing these would lead to incorrect scheduling.
