1. Schedule-Cost-Resource

The table below contains cost, resource, and schedule data for a hypothetical project.

Questions:

1. Create a network diagram for the tasks listed in the table above.
2. Calculate earliest start, latest start, and float for each task.

Task	Earliest start (ES)	Latest start (LS)	Float
A
B
C
D
E
F

3. Given the information captured in the network diagram, create a Gantt chart for the project. In the Gantt chart, picture weekends. (Assume the project begins on a Tuesday and that a week of effort is five working days long.)
4. Calculate level of effort, labor costs, and total costs per task and put the values in the appropriate cells in the first table above.
5. Assume the company being examined here has only two testers. How will this show up on a resource histogram? How should the work for Tasks D and E be leveled? What, if any, impact will the resource leveling have on the project duration?
