A) Developed by US Navy and a consulting firm in 1958 for the Polaris submarine project.

  • So, can compute the probability of achieving individual activity durations, and project milestones.
  • Uses the beta distribution, as we considered previously … and will now recap.
  • PERT requires not just expected completion times for activities, but also optimistic and pessimistic estimates.
