Which one of the following statements about Project Evaluation and Review Technique (PERT) is TRUE?
A) The expected time is given and not computed using formulas.
B) The probability of completing the project on time is 0 when the project target completion time equals the expected time.
C) The normal probability distribution is not used in PERT methods.
D) The variance in project duration is given by the sum of the variances of the critical path activities.

Question

Quizplus · Accepted Answer

In PERT, the variance in project duration is given by the sum of the variances of the critical path activities. This is because the critical path determines the duration of the project, and the variance of the critical path activities determines the total variance of the project. Therefore, option D is true while options A, B, and C are not accurate statements about PERT.
