Q: Explain the solution in statements

A project has been defined to contain the following list of activities, along with their required times for completion: ACTIVITY TME (DAYS) IMMEDIATE PREDECESSORS 1 4 A A B D E 3 A 7 6 B CD EF F 2 G 7 9 4 D I GH a. Draw the critical path diagram. b. Show the early start and early finish times. c. Show the critical path. d. What would happen if activity F was revised to take four days instead of two? Solution The answers to a, b, and c are shown in the following diagram. 1_5 B(4) 5 11 E(6) 11 18 G(7) 0 1 A(1) 1_4 C(3) 18 22 1(4) 8 10 F(2) 1_8 D(7) 8 17 H(9) Critical path: A-B-E-G-I d. New critical path: A-D-F-G-I. Time of completion is 23 days
