PERT, which is an abbreviation of “program evaluation and review technique” (PERT), is a tool that helps the managers in various ways to take care of a project. A PERT network can be made based on various activities. It is assumed that the PERT follows the Beta Probability and the expected time and variance are being computed through the two separate formulas (Render, 2018). Expected time = (4+4m+b)/6 Variance = [(b-a)/6]2 Where, a: optimistic time or a time taken by an activity when everything goes well.
