questions. (Manual solution ONLY)

a. Compute the length of each path in the network

b. Identify the critical path and indicate the minimum completion time for this project

c. Compute ES, EF, LS and LF for all the activities (you may directly show your results in the

project network graph you draw)

d. Compute slack time for all the activities (you may directly show your results in the project

network graph you draw)

e. If activity 4 is delayed by 8 months, what would happen to the completion time of the

project? How about if it is delayed by 12 months?
