A project consists of 8 activities. The activity completion times and the precedence relationships are as follows: 1. Draw the network diagram using AON model notations as shown on page 1 : What is the critical path? Calculate the minimum overall project completion time and identify which activities are critical by filling out the chart below - forward and backward pass. What is the minimum time to complete the projects? If activity B is delayed by 3 days how is the project completion time affected? Why is this the case? Will the critical path change, why or why not? If activity F is delayed by 3 days how is the project completion time affected? Why is this the case? Will the critical path change, why or why not? If you want to shorten (crash) the overall time of this project, how do you pick which activity to shorten? What information, if any, do you need? Once you shorten (crash) an activity, do you need to redo the AON, yes or no? Why or vhy not
