According to the schedule, how many days are required to complete the project?

• A. 27 days
• B. 28 days
• C. 29 days
• D. 30 days

Answer: (B)

The time to complete the project is governed by the longest chain of dependent activities, the critical path. The schedule’s total duration equals the sum of the durations along that path, and any delay on that path pushes the project finish date. If the schedule shows the final milestone landing at day 28, that means the critical path requires 28 days, so the project can’t be completed in fewer days. Slack on non-critical paths won’t shorten the overall duration because those paths aren’t the limiting factor. Remember to align the counted days with the calendar being used (calendar days versus workdays) as shown in the schedule. In this case, the indicated finish is 28 days, so that’s the required completion time.
