For the network shown in Figure P12-26 with all times indicating weeks, answer the following questions:
a. What is the impact on the end date of the project if activity I slips by three weeks?
b. By how many weeks can activity D slip before the end date gets extended?
c. If activity A slips by one week, how will the slack in activity G be impacted?
d. If activity H can somehow be compressed from seven weeks to two weeks, perhaps by adding a significant number of resources, what will be the impact, if any, on the end date of the project?
