# Project Scheduling: Network Diagrams and the Critical Path

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

Requirements:

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?

#### Solution Summary

The solution creates a network diagram with the critical path highlighted. Also, performed calculations for the float, early start and late start.
