As a side project, a friend and I are developing a probabilistic scheduling tool &quot;Probaplan&quot;. It not only uses PERT but also incorporates risks for more accurate scheduling. Using the planning, risks and PERT distributions we simulate the project in a monte carlo simulation. The result is a distribution of simulated end dates, these dates can be used to say: The probability that the project is finished before June 2016 is 80%.<p>If anyone is interested in trying out the beta version, drop me an email at andre &#x2F;at&#x2F; thebroadbaycompany.com
