Question

 Which of the following statements regarding critical paths is true?

 A. On a specific project, there can be multiple critical paths, all with exactly the same duration.

 B. The duration of the critical path is the average duration of all paths in the project network. C. Every network has only one critical path.

 D. Some activities on the critical path may have slack.

 E. The shortest of all paths through the network is the critical path.

Answer 1

Answer: option A; on a specific project, there can be multiple critical paths, all with exactly the same duration

Explanation:

There can be more than one critical path in a project. The multiple critical paths present in a project take the same amount of time to complete the activities. Hence the option A is true. The duration of critical path is the duration of all activities in the critical path and the same may not contain all the activities in a project. Hence the duration of critical path is not the average duration of all paths in the project network. Every network can have more than one critical path. Slack is the amount of time an activity can be delayed without delaying the entire project and none of the activities in the critical path have slack. Critical path is the longest path in the project’s network diagram and hence it is not the shortest of all paths through the network. Hence all other options are false.
