A project activity has an Early Start (ES) of Day 5 and a duration of 4 days. What is the Early Finish (EF) for this activity?
Day 7
Day 10
Day 9
Day 8
The correct answer is Day 8. To calculate the Early Finish (EF) of an activity, we use the formula: EF = ES + Duration - 1. In this case, we have ES = 5 and Duration = 4. Plugging these values into the formula, we get:
EF = 5 + 4 - 1 = 8
It's important to note that we subtract 1 from the result because the activity starts on Day 5 and ends on Day 8, which is a total of 4 days. If we didn't subtract 1, we would incorrectly count 5 days instead of 4.
