Topic #: 2
[All PMI-SP Questions]

Kenny is the project manager for the NHQ organization. She is creating the project duration estimates. She has stressed to her project team that they will need to create accurate and reliable project duration estimates without padding their estimates for errors or risks. Kenny is also relying on historical information to help her predict the duration of the project work. Jennifer, one of the project team members, wants to know how Kenny will account for the certain-to-happen errors and delays in the project schedule. What approach should Kenny use in the project?

  • A. Rewards and recognition for completing the project work without delays
  • B. Analogous estimating
  • C. Three-point estimates
  • D. Management reserve
Show Suggested Answer Hide Answer
Suggested Answer: D 🗳️
Management reserve is an allotment of time added to the end of the project schedule. When delays happen within the project, the delays are subtracted from the management reserve.
Incorrect Answers:
A: Rewards and recognitions are a good incentive for accurate work, but errors and delays may still happen and the rewards would not necessarily prevent delays in the project.
B: Kenny may be using some type of analogous estimating to predict activity duration, but the best answer is the reliance on the management reserve.
C: Kenny is not using a three-point estimate in this instance.

It is also called project Buffer. We are talking about error that may happen. So it is a kind of risk.

Management reserves are intended to address the unknown-unknowns that can affect a project. Management reserve is not included in the schedule baseline, but it is part of the overall project duration requirements. Depending on contract terms, use of management reserves may require a change to the schedule baseline. (PMBOK P. 202) Hence to account for certain to happen errors three point estimate is the right answer.
