Question
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.

Explanation
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
