The calculated slack values for all events lying along the critical path in a network___________________?
Show answer Hide answer
Answer: C. remains constant
Explanation
Events located along the critical path have zero total float or slack time. This lack of schedule flexibility means their calculated slack values remain constant. Throughout the entire critical path, this slack value stays at zero continuously. Total slack represents the amount of time an activity can slip without delaying the project. The critical path is defined mathematically as the longest path through the network. Any delay to an event on this critical path directly delays the final project finish date.
Project managers focus their attention and resources primarily on tasks along the critical path. Maintaining zero slack ensures that project milestones are met on schedule. Network analysis software highlights these critical events to prevent costly overruns. Option A is wrong because slack along the critical path does not increase continuously. Option B is incorrect because critical slack remains pegged at zero rather than decreasing. Option D and E are false because critical path slack is predictable and constant.
