Exposing Project Schedule Risk Hidden in Best Estimates

When we try to estimate a project completion time, often the temptation is to use a best guess completion time for each task, find the critical path, and add up the times.  This method lacks information about the project schedule risk, and if done honestly, often results in a finish time later than the due …

Project Critical Path Analysis Using Simulation

Project critical path analysis can be performed using Monte Carlo simulation as a way to determine project completion time probabilities.  In this article, we will create a network diagram in Excel and a table to perform necessary logic operations. We will assume that each task follows the PERT distribution (also called Beta-PERT).  Using past experience, …
