To best restore the schedule, which adjustment is most effective?

• A. Increasing the project budget
• B. Adding more milestones
• C. Removing a task from the project plan
• D. Reassigning all work to new resources

Answer: (C)

When a project schedule slips, the most effective way to bring it back on track is to reduce the amount of work to be done by removing a task. This directly cuts the total effort and, if the task sits on the critical path, shortens the project duration itself. In other words, eliminating work lowers the time needed to finish, which is the fastest route to restore the schedule.

Adding more milestones doesn't shrink the total work and can even add management overhead. Reassigning all work to new resources introduces transition time and learning curves, which often offset any potential speed gains. Increasing the budget doesn’t automatically speed up tasks unless there are already available, proven options to accelerate work; without that, duration remains tied to the amount of work and the sequence of activities.

So removing a task reduces the workload directly and has the clearest impact on shortening the schedule.
