The activities with zero total float form the critical path. From the table:
- Activity 1 (TF = 0)
- Activity 3 (TF = 0)
- Activity 4 (TF = 0)
- Activity 5 (TF = 0)
Thus the critical path is 1 → 3 → 4 → 5. The project duration is the EF of the last activity on the path, i.e., 17 days.
Interpretation of total float values:
- Activity 2 has a TF of 2 days, meaning it can be delayed up to 2 days without extending the overall project finish. It is not on the critical path.
- All other activities have TF = 0, indicating no scheduling flexibility; any delay will directly increase the project’s completion date.
