PMP Formula of the Week: Three-point Estimate

You are determining activity duration estimates and one of your colleagues suggests using a three-point estimate. What is the primary advantage of this method?

A. Three points, rather than one, improve the accuracy of the activity duration estimate.
B. It is always preferable to consider three opinions instead of just one.
C. The best case and worst case scenarios are factored into the estimate.
D. Team members will provide the most accurate estimates.

Reveal Answer

The correct answer is A.

Both answer C and D are components of the three-point estimate, but not the primary advantage of the method. Answer B is incorrect because three opinions may not result in three different estimates.
