Comprehensive Project Management And Scheduling Techniques For Students Practice Test

Activities are the actual work tasks that take time to complete and need resources. Milestones are zero‑duration points that mark the completion of a phase or a key result. They don’t add time to the schedule, but they provide clear checkpoints. Milestones are useful because they give a simple, widely understood signal of progress for stakeholders and make the schedule easier to follow by breaking it into meaningful phases. They let you verify you’ve reached a major achievement before moving on, without tracking every single task in detail. In practice, you plan activities to lead up to a milestone; when the milestone is reached, you can review progress and plan the next set of work. The other ideas mix up duration: activities aren’t zero‑duration tasks, and milestones aren’t tasks with duration.
