In the LAN project, activities C and D can be done concurrently. Suppose instead that activity C is an immediate predecessor of activity D. (Perhaps they use the same employees, and these employees can perform only one activity at a time.) How does the AON diagram change? How much does the project completion time increase? What is the new critical path? (You can assume that activity E is still an immediate successor of activity C. That is, it doesn’t need to wait for activity D to finish.)
