An externally imposed project completion time sets the project duration at 75 days. The critical path of the project is established as 75 days, with a standard deviation of 3 days. What could be the maximum project float available

3 days

Step-by-step explanation:

This can be seen under Schedule management (Initiating)

Project float is simply the difference between the completion period externally imposed and the estimated time duration of the project (usually this is equal to the critical path length). The difference in this case is 0 because

Externally imposed project date = 75 days

Estimated duration of project = 75 days

Hence, a difference in these will be 0

However, a standard deviation of 3 days was giving (This implies that there is a + / - 3 days in the critical path from the estimated project duration).

Hence the maximum float in this case will be 0 + 3 = 3 days
