The advantages of PERT

We have seen that by requesting multivalued activity duration estimates and calculating expected dates. PERI focuses attention on the uncertainty of forecasting. We can use the technique to calculate the standard deviation for each task and use this to rank them according to their degree of risk. Using this ranking, we can see. for example, that activity F is the one over which we have greatest uncertainty, whereas activity C should, in principle, give us relatively little cause for concern.

If we use the expected times and standard deviations for forw ard passes through the network we can. for any event or activity completion, estimate the probability of meeting any set target. In particular, hy setting target dates along the critical path, we can focus on those activities posing the greatest risk to the project's schedule.
