• Enter the "Immediate Predecessors" information into cells B4-B11
• Compute and enter the ES, EF, LS, LF, and Slack times for each activity into columns D through H as indicated
• Answer the following
  • How long will the project take? (Enter value)
  • What is the critical path?

18. For the project from the question above, what is the impact on total project duration if Activity C is delayed by 1 period - that is, it took 1 period longer than originally planned? Explain.

19. For the project from the question above, what is the impact on total project duration if Activity D is shortened by 1 period? Explain.
