Consider the following project. Calculate the expected activity times for all the activities.
Question:
Consider the following project.
| Activity | Predecessors | a | m | b |
|---|---|---|---|---|
| A | Start | 2 | 5 | 14 |
| B | Start | 3 | 5 | 13 |
| C | A | 3 | 8 | 13 |
| D | C | 1 | 4 | 7 |
| E | B, C | 6 | 9 | 18 |
| F | B | 6 | 7 | 14 |
| G | D, E | 7 | 10 | 19 |
| H | E, F | 4 | 6 | 14 |
| I | F | 3 | 4 | 17 |
Calculate the expected activity times for all the activities.
PERT Expected Time:
PERT expected time is defined as the expected average time taken by each activity to complete. It is calculated by taking three-time estimates of every activity. With the help of the expected time, the project manager can determine the project's completion time.
