Free PMI Project Management Professional (PMP) Practice Question
A project manager is calculating the Late Finish (LF) for an activity. The Late Start (LS) is Day 10, and the activity duration is 5 days. What is the Late Finish for this activity?
The correct answer is Day 14. The formula for calculating Late Finish (LF) is: LF = LS + Duration - 1. In this case, LS = 10 and Duration = 5. Therefore, LF = 10 + 5 - 1 = 14. It's important to note that we subtract 1 from the result because the activity starts on Day 10 and ends on Day 14, which is a total of 5 days. If we didn't subtract 1, we would incorrectly count 6 days instead of 5. This calculation is crucial for determining the latest an activity can finish without delaying the project end date.
