I have uploaded a new video to my YouTube Channel - this one is about a Problem-Solving Technique called PERT Analysis. PERT (Programme Evaluation and Review Technique) is used by Project Managers to help estimate the duration of a task here there is a high degree of uncertainty. It takes into account the optimistic time, most likely time, and pessimistic time that a task can be completed. The name PERT is still used to describe Project Network Diagrams and Gantt Charts - so it is often a confused with other techniques. I teach PERT in my Project Management classes and is a favourite of mine for test questions. Check out the video on YouTube below.
