Which technique involves performing critical path activities in parallel, increasing risk and potential rework?

• A. Fast Tracking
• B. Crashing
• C. Critical Chain Method
• D. Critical Path Method (CPM)

Answer: (A)

When critical path activities are performed in parallel to shorten the schedule, you accept higher risk and more potential rework. This approach is Fast Tracking. It overlaps tasks that would normally be done sequentially, so information from one activity may not be ready for the next, increasing the chance that changes or mistakes propagate and require rework. The other techniques focus on different levers: crashing shortens the schedule by adding resources (usually at higher cost), the Critical Path Method identifies the longest path without inherently changing the execution order, and the Critical Chain Method emphasizes buffer management around resource constraints rather than parallelizing critical-path work.
