When planning to add personnel to tasks imposing time constraints on the duration of a project, which of the
following should be revalidated FIRST?

A.
The project budget

B.
The critical path for the project

C.
The length of the remaining tasks

D.
The personnel assigned to other tasks

Explanation:
Since adding resources may change the route of the critical path, the critical path must be reevaluated to
ensure that additional resources will in fact shorten the project duration. Given that there may be slack time
available on some of the other tasks not on the critical path, factors such as the project budget, the length of
other tasks and the personnel assigned to them may or may not be affected.
