Which one of the following estimate types is a form of expert judgment?

A.
Parametric estimate

B.
Analogous estimate

C.
Bottom-up estimate

D.
Definitive estimate

Explanation:
An analogous estimate is a form of expert judgment because it relies on historical information. The
historical information, assuming that it is accurate, serves as the conduit to the expert that created
the historical information.
Answer option C is incorrect. A bottom-up estimate creates an activity duration estimate for each
work package in the WBS.
Answer option A is incorrect. Parametric estimating uses a parameter, such as 10 hours per fixture
installation, as a base to predict the duration of the project.
Answer option D is incorrect. A definitive estimate, also known as a bottom-up estimate, accounts
for the cost of each work package.
