The pert formula
Webb20 juli 2024 · In the PERT formula, optimistic time (OT) is the shortest possible duration for the work. Pessimistic time (PT) is the longest possible duration. Most likely time (LT) is the most realistic estimate. In order to calculate expected time (ET), use the following formula: [OT + (4 x LT) + PT] ÷ 6 = ET Use this widget to perform a PERT analysis ... WebbPERT is a variation on Critical Path Analysis that takes a slightly more skeptical view of time estimates made for each project stage. To use it, estimate the shortest possible time each activity will take, the most likely length of time, and the longest time that might be taken if the activity takes longer than expected.
