The critical path on a network chart is established by connecting sequential events possessing____________________?
Show answer Hide answer
Answer: B. minimum slack
Explanation
The critical path consists of a sequence of connected events and activities having the minimum total slack. Activities on the critical path determine the absolute minimum duration required to complete the entire project. Any delay experienced by an activity located on the critical path immediately extends the final project completion date. Network analysis charts map out project tasks as interconnected nodes and arrows representing sequential workflows. Total slack or float is the amount of schedule leeway available to a task without postponing project completion. Identifying the critical path allows managers to focus supervisory attention and resources on the most time-sensitive tasks.
Option A is incorrect because maximum slack corresponds to non-critical tasks with extensive scheduling flexibility. Option C is wrong because average slack does not define the longest constraining sequence of project activities. Option E is incorrect because the critical path is calculated mathematically using network times rather than subjective judgment.
