Question 3: As a result of a bank merger, two financial processing software systems must be integrated. The systems integration team has come up with the following tasks, their predecessor relations and estimates for task durations and crash costs: Activity A B C D E F G H Immediate Predecessor(s) Normal time 15 A 9 A 10 B, C 3 9 D 10 DE 10 F, G 7 Crash time 10 8 6 3 5 7 8 7 Normal cost ($) Crash cost ($) 800 3800 700 1000 1500 2500 3000 3000 1000 1800 1400 2300 800 1000 2000 2000 a. Draw the project network. b. Identify the critical path(s). c. Find the total project completion time and total project cost using the normal times. d. Find the total project completion time and total project cost if the project must be completed two weeks early. e. Find the shortest time in which the project can be completed. f. Assume that in addition to the activity costs there are overhead costs (for things such as support staff, heating, rent, etc.) of $500 that are charged for every week that the project is active (and stop as soon as the project is completed). Find the crashing schedule that minimizes total project cost
