    Using the following activities and their relationships contract a PDM network.
    1. A Start Milestone starts the project
    2. Activities A and B can start at the milestone
    3. Activity C follows the completion of A
    4. Activity D can start after A finishes
    5. Activity E cannot start until B is finished
    6. Activity F starts after D and E have finished
    7. Activity G starts after C finishes
    8. Activity H can start after E finishes
    9. The project finishes after G, F and H finishes.

    Use the following durations in working days:

    1. Start and Finish milestones = 0 days
    2. A = 4 days
    3. B = 2 days
    4. C = 6 days
    5. D = 7 days
    6. E = 4 days
    7. F = 5 days
    8. G = 5 days
    9. H = 4 days

    1. Calculate the Early and Late dates for each activity.
    2. What is the latest date C can finish?
    3. What is the latest date E can finish?
    4. Calculate total float for each activity.
    5. What activities are on the critical path?
    6. What is the early finish date of the project?
