a. Draw the network and determine the ES, LS, EF, LF, and slack for each activity and the total project time.

b. Draw a Gantt chart for the network using the ES times for each activity

c. Draw a resource loading profile.

d. What is the maximum number of resource units needed?

e. What is the utilization percent?

f. Use the resource leveling technique – leveling within slack - to determine how the project can be done with fewer resources in the same amount of time. Draw a revised Gantt chart and resource loading profile for your solution.

f. What is the utilization percent now?
