Which term describes tasks that must be finished before another task can start?

• A. Predecessor
• B. Successor
• C. Milestone
• D. Constraint

Answer: (A)

In project scheduling, tasks that must be finished before another can start are called the predecessor. This sets the sequence: the predecessor completes first, and the next task (the successor) can begin. The relationship is often finished-to-start, meaning the successor cannot start until the predecessor finishes. A milestone is simply a notable point or event, not a task dependency. A constraint is a limitation that affects scheduling but does not define a direct predecessor–successor link. For example, if Task A must be completed before Task B begins, Task A is the predecessor and Task B is the successor.
