A project involving the development of a new product platform for the next year model consists of totally 15 activities. The immediate predecessors and activity time (in weeks) are shown below. Complete the network diagram and find The total project completion time = ? (4 point ) Which Activity is on the Critical Path ? (4 points) The slack time for activity M= ? (4 points) If activity I is delayed by 1 more week, project completion time = ? (4 points) Note: This is a MULTIPLE-ANSWER problem, you have to select one correct answer for each of the 4 questions. The total project completion time =27 weeks The total project completion time =28 weeks The total project completion time =29 weeks The total project completion time =30 weeks Activity G is on the Critical Path Activity H is on the Critical Path Activity I is on the Critical Path Activity J is on the Critical Path The slack time for activity M=0 week The slack time for activity M=2 weeks The slack time for activity M=4 weeks The slack time for activity M=6 weeks If activity I is delayed by 1 more week, project completion time will be 26 weeks If activity I is delayed by 1 more week, project completion time will be 27 weeks If activity I is delayed by 1 more week, project completion time will be 28 weeks If activity I is delayed by 1 more week, project completion time will be 29 weeks
