What is the longest path through the project network that determines the shortest possible completion time?

• A. Critical Path
• B. Slack
• C. PERT
• D. Gantt Chart

Answer: (A)

Think of the project as a network of dependent tasks. The overall finish time is driven by the longest chain of activities that must happen in sequence. That longest chain determines the earliest possible completion date because any delay on it pushes the entire project forward. This chain is known as the critical path. It typically has zero slack, meaning there’s no wiggle room on those tasks without delaying the finish. Other terms don’t set the project duration on their own: slack is the allowable delay for non-critical tasks, PERT is a probabilistic estimation method, and a Gantt chart is just a visual timeline of activities. So the longest path that fixes the earliest finish is the critical path.
