Question

While doing the project planning of a Construction: project, using PERT, it is intended to identify the variance of the project. This can be done by:

• A. Sum of variance of the activities along critical path of the project
• B. Sum of squares of the total floats of all activities in the project
• C. Sum of squares of free floats of all activities along the critical path of the in the project.
• D. Sum of variance of all activities of the project

Answer 1

Answer:

A. Sum of variance of the activities along critical path of the project

In PERT, the project variance is calculated by summing the variances of the activities that lie on the critical path. The activities on the critical path are the ones that, if delayed, would delay the entire project. Therefore, understanding the variance along this path can give an indication of the potential variation in the project's duration.
