hard · Project Management Professional hybrid

Peakstone Rail is developing a new signaling system. The network diagram shows four paths: Path 1 is 14 weeks, Path 2 is 18 weeks, Path 3 is 21 weeks, and Path 4 is 19 weeks.

If an activity on Path 3 is delayed by 2 weeks, what is the effect on the project's completion date?

  1. The completion date will shift by 4 weeks due to the merge bias at the end of the project.
  2. Path 2 will become the new critical path, resulting in no overall project delay.
  3. The project will be delayed by 2 weeks, as Path 3 is the critical path.
  4. The project will not be delayed, as Path 3 has 2 weeks of total float.
