Question

When a project has a positive total slack, some activities can be ________ without jeopardizing completion of the project by its required completion time. When a project has negative slack, some activities need to be ________ to complete the project by its required completion time.

Answer 1

Delayed, accelerated

Step-by-step explanation:

Total or aggregate slack, is the term which is defined for the activity, is the time that this activity could delayed without impacting on the final date of the project.

It can be computed as the:

Smaller value of Late finish - Early finish field

and

Late start - Early start field

So, when project has positive total slack, few activities delayed the completion of project and when the project has negative total slack, then few activities accelerated to finish the project.
