You manage a project with 10 activities. activities a1, a3, a5, a9 form the critical path. as you have a large budget for the project, you are considering crashing activity a2, which has the potential to shorten the time of a2 by 3 days.
what do you think about this opportunity?
o a good idea, it will reduce the project duration by 3 days.
o a bad idea, as a2 is not on the critical path.

A bad idea, as A2 is not on the critical path.

Explanation:

Critical path is a path which is the shortest path of doing the activity.

When an activity is in critical path, then there is a benefit of crashing it. Or if it is not the part of critical path then the benefit is to crash the activity and then apply the spare resources in some activity which is a part of critical path.

Thus, crashing A2 which is not a part of critical path and then not deploying the resources on to the activities of critical path will not provide for any benefit.

It is ultimately not a wise idea.
