- Consider the given Network Diagram Data for a Large Project Y. All duration estimates or estimated times are in weeks and the network proceeds from Node 1 to Node 8.
| Activity | Initial Node | Final Node | Estimated Duration |
| A | 1 | 2 | 14 |
| B | 1 | 3 | 12 |
| C | 1 | 4 | 8 |
| D | 2 | 3 | 5 |
| E | 2 | 5 | 10 |
| F | 3 | 4 | 6 |
| G | 4 | 5 | 4 |
| H | 4 | 6 | 10 |
| I | 5 | 6 | 10 |
| J | 5 | 8 | 12 |
| K | 6 | 7 | 8 |
| L | 7 | 8 | 15 |
- Draw an Activity-on-Arrow (AOA) network diagram representing the project. Put the node numbers in circles and draw arrows from node to node, labelling each arrow with the activity letter and estimated time.
- Identify all the paths on the network diagram and note how long they are.
- What is the critical path for this project and how long is it?
- What is the shortest possible time it will take to complete this project?
