(8 marks) Task effort 3.2 Draw the network (AOA) diagram to show the order in which all the activities will be undertaken in this project. The diagram must be clearly labelled. (6 marks) 3.3 List all the possible paths for this project with their total durations. (5 marks) 3.4 Clearly identify and briefly explain the critical path for this project. (7 marks) 3.5 This network is expected to be up and running within 4 months from the time the work on the project is started. Does this opening date appear feasible? (4 marks)
