| D | A, \(B\) | 4 |
| E | \(B , C\) | 1 |
| \(F\) | D | 2 |
| G | E | 9 |
| H | \(F , G\) | 1 |
| I | \(H\) | 6 |
| \(J\) | \(H\) | 5 |
| \(K\) | \(I , J\) | 2 |
- Complete an activity network for the project on Figure 1.
- On Figure 1, indicate:
- the earliest start time for each activity;
- the latest finish time for each activity.
- State the minimum completion time for the decorating project and identify the critical path.
- Activity \(F\) takes 4 days longer than first expected.
- Determine the new earliest start time for activities \(H\) and \(I\).
- State the minimum delay in completing the project.
