PMP Exam Preparation: Introduction to Three Point Estimating

Sir Ganttalot helps you prepare for the PMP exam by explaining Three-Point Estimating. The video explains how to derive a Mean Estimate, how to calculate Standard Deviation (Sigma), and how to calculate Variance. In all cases both Triangular and PERT techniques are addressed. A second, related, video then shows how to apply Sigma values to calculate Confidence Levels for Estimates

why do we have to take 4times the most likely value ?

[SirGanttalot]

The technique called PERT (Project Evaluation Review Technique) uses a weighting factor of 4 as a standard. This is because overall it has been shown to be the best, simple, setting, giving the most accurate results. Of course, for your own needs in special circumstances you can set different weightings. In Microsoft Project for example you can adjust the PERT weights. For the PMP exam though, use a weighting of 4 for PERT.
