PERT (Program Evaluation and Review Technique) uses a weighted average of the most optimistic time (O), most pessimistic time (P), and four times the most likely time (M) to calculate the expected time. The formula is E = (O + 4M + P) / 6. This approach takes into account both the best and worst-case scenario as well as the most likely time for completing an activity.
