Listen to Rod. Besides the fact that Risk Analysis software will do all
that and more for you, PERT has been found to be statistically unsound.
Yes, I know it's been in use for years. I first learned and applied it in
the 1970's, and it had been around for a while by then. Nonetheless, it's
not a valid method for getting representative risk-based estimates of task
durations. Monte Carlo analysis is.

Hope this helps.
