What will happen to a project if a project manager elects to do resource leveling?

A.
The project will need more resources.

B.
The project schedule will increase in duration.

C.
The critical path will likely change.

D.
The project will finish faster than schedule.

Explanation:
Resource leveling restricts the amount of time a project resource can be used in a given time period. If a project team member is scheduled to work ten hours a day, but resource leveling restricts this to eight hours per day, then the schedule will increase as it will take more calendar days to complete all of the scheduled work. Answer option D is incorrect. The project will not finish faster, but it will take longer to complete.
Answer option C is incorrect. The critical path is not likely to change based on resource availability. It’s possible that as a result of leveling the project manager changes the order and duration of activities, but leveling itself would not cause this happen. Answer option A is incorrect. The project will need more resources if the project demands to reach a certain deadline and maintain a level amount of resource utilization. There’s no guarantee, however, that by adding resources to the project that the project will finish in less time and some activities, such as testing, may be of fixed duration.
