PMI-SP Exam - Topic 3 Question 25 Discussion

Actual exam question for PMI's PMI-SP exam
Question #: 25
Topic #: 3
[All PMI-SP Questions]

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?

Show Suggested Answer Hide Answer
Suggested Answer: B

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.

I thought GERT was a thing too, but I guess not for this method!

The formula is key! It's PERT, not GERT.

Wait, does it really take that much time to do this?

A three-point estimate is all about optimistic, pessimistic, and most likely durations.

I’m confused about GERT and PERT. I thought they were the same, but I think GERT is different. I need to double-check that before answering.

I recall something about PERT being related to three-point estimates, and it uses a specific formula. I think it’s option C that describes that correctly.

I remember studying the three-point estimate, and I think it involves estimating optimistic, pessimistic, and most likely durations for each activity.

I’m a bit unsure, but I think the average is calculated after getting those three estimates. Was it option A or B that mentioned that?

This is a good question. Based on my understanding, when using LINE_BREAKER, SHOULD_LINEMERGE should be set to Auto to properly merge the lines back together. I'm fairly confident in that.

Okay, let's see. For the payment type, a Radio button makes the most sense since the customer can only select one option. And for the payment amount, a Currency element would be best to handle the formatting and validation. I feel pretty confident about those choices.

Hmm, I'm not entirely sure about this one. I know we can use SSH keys, PATs, or certificates to authenticate agents, but I'm not 100% confident which one is the best choice here. I'll have to think it through carefully.
