Which of the following can be calculated for an activity once ES, EF, LS, and LF have been calculated for the activity?
A) expected project duration
B) slack time
C) potential for crashing
D) variance in project duration
E) the relative time position for when the activity will be completed

Question

Quizplus · Accepted Answer

Slack time can be calculated by subtracting the activity's EF from its LF, or its LS from its ES. This provides information on the amount of time an activity can be delayed without delaying the project's overall completion time.

Answer: D 
 Variance in project duration can be calculated by summing the variances of individual activities along the project's critical path. ES, EF, LS, and LF are used in determining individual activity variances, so this information is needed to calculate the project's overall variance.
