Consider a project that has been modeled as follows:

Requirements:

1. Draw the PERT/CPM network for this problem. For this problem please draw the network by hand. (Paste an image of your network on the slide.)
2. Determine ES, EF, LS, LF, and slack for each activity.
3. Determine the project's expected completion time and its critical path.
4. Can activities E and G be performed simultaneously without delaying the minimum project completion time? Explain your answer.
5. Can one person perform A, G, and I without delaying the project? Explain.
6. By how much can activities G and L be delayed without delaying the entire project?
7. How much would the project be delayed if activity G was delayed by 7 hours and activity L was delayed by 4 hours? Explain your answer.
