You are the project manager of the NHQ project. This project is slightly larger than the TR project,
in which you also served as the project manager. You decide to use the actual activity duration of
the GTR project as a basis for your current NHQ project. This, you reason, will save time for your
project, as the previous project has provided the information. Which one of the following terms
best describes the action you are doing in this scenario?

A.
You are creating an analogous estimate.

B.
You are creating a bottom-up estimate.

C.
You are relying on expert judgment.

D.
You are creating a rough order of magnitude estimate.

Explanation:
This is an example of analogous estimate as you are creating an analogy between two similar
projects. This estimating approach is also known as a top-down estimate type, and is somewhat
unreliable.
Answer option C is incorrect. Expert judgment relies on experts, consultants, or subject matter
experts to guide your project decisions. An analogous estimate is a form of expert judgment, but
this is not the best choice for this question.
Answer option B is incorrect. A bottom-up estimate creates an activity duration estimate for each
work package in the WBS. It is the longest estimate type to create, but it also the most reliable.
Answer option D is incorrect. A rough order of magnitude estimate is a quick estimate, usually for
project costs, that often has a broad range of variance attached to the estimate.
