A project has been defined to contain the following list of activities along with their required times for completion.
| Activity Number | Immediate Activity | Time (weeks) | Predecessors |
| 1 | Collect Requirements | 3 | |
| 2 | Analyze processes | 2 | 1 |
| 3 | Analyze data | 2 | 2 |
| 4 | Design processes | 6 | 2 |
| 5 | Design data | 3 | 3 |
| 6 | Design screens | 2 | 3,4 |
| 7 | Design reports | 4 | 4,5 |
| 8 | Programming | 5 | 6,7 |
| 9 | Test & document | 7 | 7 |
| 10 | Installation | 2 | 8,9 |
- Based on this project, create a network diagram, and GANTT chart for this project.
- Calculate the overall duration of this project, and show the critical path on your network diagram or GANTT chart.
- What would happen to the project plan if activity 6 were revised with an estimated time of six weeks?
- Assume that your team is in its first week of the project and has discovered that each of the activity duration estimates is wrong. Activity 2 will take only two weeks to complete. Activities 4 and 7 will each take three times longer than anticipated. All other activities will take twice as long to complete as previously estimated. In addition, a new activity, number 11, has been added. It will take one week to complete, and its immediate predecessors are activities 10 and 9. Adjust the network diagram or GANTT chart, and recalculate the earliest expected completion times.
