Dear planners
I am very new into planning and I am writing my master thesis about scheduling and risk management.
Can someone explain me if the PERT technique is probabilistic or just deterministic? I read some articles that say it is probabilistic, because the three estimates of time together determine the probability distribution of the completion time on the critical path. However, all the data are determined by the deterministic methods and all computed values are completely determined by the data used to compute them, therefore the duration time will be all the time same and doesn’t matter how many times do you calculate duration, it will be all the time same.
