During PERT network evaluation, the critical path is traced by linking events characterized by___________________?
Show answer Hide answer
Answer: C. zero sldck
Explanation
The critical path is formed by linking events with zero total slack. Zero slack indicates that any task delay will directly extend project duration. Network evaluation identifies bottlenecks by locating paths with no scheduling flexibility. Slack time represents the amount of leeway available to delay a scheduled task. Project evaluation and review technique uses probabilistic time estimates for complex jobs. Calculated early and late event times determine the available float for activities.
Project managers monitor zero slack milestones very closely during project execution phases. Identifying critical milestones helps allocate extra workforce to prevent project completion delays. Engineering supervisors focus entirely on tasks possessing zero float during tight schedules. Positive slack means tasks have extra scheduling flexibility and are not critical. Negative slack indicates the project schedule is currently running behind target deadlines. Dummy activities are used only for logic representation and do not define paths.
