PMI Exam PMI-SP Topic 3 Question 25 Discussion
Topic #: 3
Andy is the project manager of the NHGQ project for his organization. He has elected to use a three-
point estimate for his project. His project team, however, is complaining about participating in this
estimate type because of the time it takes to predict the duration of activities. Andy, as the project
manager, tells the project team that they must create the time estimate, as it will help this project
and future similar projects. What is a three-point estimate?
A three-point estimate requires that each activity be estimated for its optimistic, most
likely, and pessimistic duration. Once the three
estimates have been created, an average of the duration estimates is found and this is the recorded
duration for the project work.
Answer option A is incorrect. This is not a complete explanation of a three-point estimate.
Answer option C is incorrect. This is a definition of PERT, a similar time estimating technique.
Answer option D is incorrect. This is definition of PERT, but this answer uses the term GERT so it is
not a valid choice.
