What term describes a delay between tasks in a project schedule?

• A. Gantt Chart
• B. Finish-to-Start Relationship
• C. Change Order
• D. Lag

Answer: (D)

Lag is the waiting period inserted between the finish of one task and the start of the next. In scheduling, tasks are linked with dependencies (for example, a task can’t start until the previous one finishes). When you want a delay between those tasks, you add a lag to the dependency, so the successor starts after a specified amount of time. This captures real-world pauses like waiting for approvals, resource availability, or external inputs. A Gantt chart simply visualizes task timing and durations. The finish-to-start relationship defines the sequencing, but it’s the lag that introduces the actual delay. A change order relates to scope or cost changes, not the timing gap between tasks.
