for the "determine data needs" activity of a project, the optimistic estimated duration is 10 days, the pessimistic estimated duration is 20 days, the most likely time is 15 days. what is the expected duration of completing this activity?

This is a PERT  (Program Evaluation and Review Technique) question and the expected duration of completing this activity can be solved using the formula below.

 Pert Expected Duration Estimate = ║Optimistic Duration + (4 x Most Likely Duration) + Pessimistic Duration║/6.

15 days = Most likely Activity Duration.

10 days = Optimistic Activity Duration

20 days = Pessimistic Activity Duration

Substituting these values, we will have

(10 +(4 X 15) +20)/6. The pert estimate is therefore calculated as 15 days

The expected duration of completing this activity = 15 days.
