CAPM Practice Question

The critical path determines the shortest possible project duration. Any delay in activities on the critical path directly affects the overall project completion time. When an activity on the critical path is delayed, the entire project is delayed by the same amount since there is no slack or float available on the critical path. This is why project managers closely monitor critical path activities - they directly impact the project delivery date.

Activities not on the critical path have float (or slack) and can be delayed within that float without affecting the project completion date.
