12–16 Consider the following network for a small MIS project (all times are in days; network proceeds from node 1 to node 10):

a. Identify the critical path.

b. Calculate the total network slack time.

c. Suppose that activities A, B, and C all utilize the same manpower base, and shortening any one of these three activities causes one of the other two to increase by the same amount. Can network replanning, only for these three activities, shorten the length of the critical path?

d. Repeat parts

a, b, and c assuming that the estimated time for job C is 4.
