Planning & EstimatingCâu 640 / 700
In critical path method (CPM) scheduling, which statement is correct?
a.The critical path is the shortest chain of activities in the network.
b.Activities on the critical path have the most float and can slip freely without affecting the finish date.
c.The critical path is the longest path through the network and has zero float; delaying any critical activity delays the whole project, while delaying a non-critical activity only within its float does not.
d.Float is the extra profit margin built into the project schedule.
Giải thích
Correct: the critical path is the longest continuous path of dependent activities and determines the project duration; its activities have zero float, so any delay there pushes the completion date, whereas non-critical activities can slip within their available float without moving the finish. The critical path is the longest, not shortest, path. Critical activities have zero float, not the most. Float is scheduling slack, not profit.
