Problem 1: 33 points. Assume that you are supporting a project manager, and have been given the follow project activity network. You can assume the times are certainties (use the CPM method). 1) Do the Forward and Backward Pass on this network. You can write all Earliest and Latest Times and Slack in this table instead of writing on diagram. (20 points) Activity, Duration ES EF LS LF Slack A, 6 B,3 C, 4 D, 6 E,9 F, 6 2) What is the project completion time? What is the critical path? (7 points) 3) Suppose that I tell you that one non-critical activity has increased by 2 weeks. Is there any non-critical activity that, if increased by 2 weeks, would NOT delay your project? Which one is it and why? (6 points). . E . End Start F D B
