a technique used to estimate cost or duration by applying an average of optimistic, pessimistic, and most likely estimates when there is uncertainty with the individual activity estimates PERT: program evaluation and review technique; uses three estimates to define an approximate range for an activity's duration: 1.

Optimistic (tO): activity duration based on analysis of the best-case scenario for the activity 3. Pessimistic (tP): activity duration based on analysis of the worst-case scenario for the activity Beta Distribution >> expected duration (tE) = (tO+4tM+tP)/ 6 duration estimates based on three points with an assumed distribution provide an expected duration and clarify the range of uncertainty around the expected duration T&T of Estimate Activity Durations
