Suggested Answer:D🗳️
The only statement that is true is that the critical path shows the project's earliest date for completion. A critical path is the sequence of project activities, which add up to the longest overall duration. This determines the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date (i.e. there is no float on the critical path). A project can have several, parallel, near critical paths. An additional parallel path through the network with the total durations shorter than the critical path is called a sub-critical or non-critical path. These results allow managers to prioritize activities for the effective management of project completion, and to shorten the planned critical path of a project by pruning critical path activities, by "fast tracking" (i.e., performing more activities in parallel), and/or by "crashing the critical path" (i.e., shortening the durations of critical path activities by adding resources). Incorrect Answers: A: The critical path can be, and often is, crashed with extra resources in an attempt to recover the project schedule. B: The critical path is the longest path to project completion. C: There can be more than one critical path, as two paths in the project network diagram can both take the same amount of time and be longer than any other paths in the project.
