The variance for a project's duration is given by ______.
A)the sum of the variances for all its activities
B)the sum of the variances for all its critical activities
C)the sum of the standard deviations for all its activities
D)the sum of the standard deviations for all its critical activities

Question

Quizplus · Accepted Answer

The variance for a project's duration is determined by the sum of the variances for all its critical activities. This is because the critical path determines the project's duration, and any variability in the critical activities directly impacts the overall project duration. Non-critical activities have slack and thus their variances do not directly affect the project's total duration variance.
