The time is in weeks. Propose critical path and another TWO (2) possible paths other than critical path, with information on the total project time. (10 marks) b) Compute a cost/time slope for each activity that can be crashed. Slope (crash cost - normal cost)/(crash time - normal time) (4 marks) Evaluate the time and cost factor, propose a solution where the project can be shorten to 12 weeks and what are the total cost required by modifying the critical path?
