Case Study: Project Management Critical Path Method The network below represents a project being analyzed by the critical path method. Activity duration in weeks, are given in the following table and represented by the network diagram below: A B C D E F G H I J 3 2 12 3 5 1 7 2 10 6 a) What task must be on the critical path, regardless of activity duration? (2 marks) b) What is the duration of path A-B-E-H-J? (3 marks) c) What is the critical path of this network? (3 marks) d) What is the length of the critical path? (3 marks) e) What is slack time at activity H? (3 marks) f) What is the Late Finish of activity H? (3 marks) g) If activity C were delayed by two weeks, what would happen to the project duration? (3 marks)
