Create a network diagram and a Gantt chart for the project tasks. Ask your instructor if you are permitted to use software such as Microsoft Project to help you prepare your diagrams.

What is the planned duration for the testing project?

What is the critical path for the testing project?

For each task NOT on the critical path, calculate the amount of slack available.
