Objective Estimation of Activity Time in Project Management

Abstract

A better project evaluation and review method is suggested and put to the test. By using this technique, the subjectivity and ambiguity surrounding the predicted time of the intended activity would be diminished. The three-time estimate is put through a normalcy test to achieve this. This method would improve activity time estimation’s precision and objectivity. However, when several project works were examined, the propose PERT approach generated results for activity and project durations, variances, and project duration probability that were comparable to those of traditional PERT. The goal of the paper is to eliminate the uncertainty that exists when project evaluation review technique estimates activity time. The data demonstrates that all three-time estimates are normally distributed. The unique strategy utilized in this work is the first to overcome ambiguity in activity time estimation.
