a) As we reduce the project duration, do the number of critical paths increase or decrease? Why? (3 points) b) Why do we keep focusing on the critical path when reducing the project duration? How do you reduce the duration if there are more than 1 critical path? (4 points) b) Why is it important to choose the activity or activities with the least slope to reduce the duration? Explain. (3 points)

c) Consider the above diagram. Assume the slope for activities A, B, C, D, E and F in the diagram provided are 50, 20, 30, 20, 20 and 10 respectively. You cannot crash activity F but you can crash all others. Activity durations are provided under each activity name. Which activity or activities will you crash next to reduce this projects duration? Why? Clearly explain your answer. (10 points)
