Which of the following is not typically considered a project scheduling technique?

• A. Gantt Chart
• B. PERT
• C. Slack
• D. Critical Path Method (CPM)

Answer: (C)

The concept being tested is the difference between scheduling techniques and schedule measurements. Gantt charts, PERT, and the Critical Path Method are all methods used to plan, visualize, and analyze the sequence and timing of activities. They help you determine how long the project will take, which tasks depend on others, and where time is allocated. Slack, on the other hand, is not a technique you use to create the schedule. It’s the amount of time an activity can be delayed without delaying the project's finish date. It’s a result you derive from the scheduling calculations—especially from CPM and PERT analyses. Tasks on the critical path have zero slack, while other tasks have positive slack that shows the schedule’s flexibility. So the best choice is Slack, because it represents a measure of flexibility, not a scheduling technique.
