Explanation:
Critical path is the longest path in the network diagram which determines the minimum duration required to complete the project. Any change in the duration of an activity can affect the critical path of the project. The given question states that the duration of activity f is changed to 10 days and we need to determine the impact on the critical path and total duration of the project.
Impact on Critical Path:
To determine the impact on the critical path, we need to calculate the earliest start time (EST), earliest finish time (EFT), latest start time (LST), and latest finish time (LFT) for each activity in the network diagram. Using these values, we can calculate the total duration of the project and the critical path.
Before changing the duration of activity f:
Activity | Duration | Predecessor | EST | EFT | LST | LFT | Slack
------------|----------|-------------|-----|-----|-----|-----|------
A | 3 | | 0 | 3 | 0 | 3 | 0
B | 2 | A | 3 | 5 | 3 | 5 | 0
C | 5 | B | 5 | 10 | 5 | 10 | 0
D | 4 | C | 10 | 14 | 12 | 16 | 2
E | 2 | C | 10 | 12 | 10 | 12 | 0
F | 6 | D,E | 14 | 20 | 16 | 22 | 2
The critical path is A -> B -> C -> D -> F with a total duration of 20 days.
After changing the duration of activity f to 10 days:
Activity | Duration | Predecessor | EST | EFT | LST | LFT | Slack
------------|----------|-------------|-----|-----|-----|-----|------
A | 3 | | 0 | 3 | 0 | 3 | 0
B | 2 | A | 3 | 5 | 3 | 5 | 0
C | 5 | B | 5 | 10 | 5 | 10 | 0
D | 4 | C | 10 | 14 | 12 | 16 | 2
E | 2 | C | 10 | 12 | 10 | 12 | 0
F | 10 | D,E | 14 | 24 | 16 | 26 | 2
The critical path is A -> B -> C -> D -> F with a total duration of 19 days.
Conclusion:
Hence, we can see that the critical path remains the same but the total duration of the project changes to 19 days. This is because the change in duration of activity f has affected the EST and EFT of activity F, which has led to a change in the total duration of the project. However, the critical
