Finish-finish dependency in scheduling means:

• A. The start of one task must occur before the start of the other
• B. The finish of one task must occur before the finish of the other
• C. The start of one task must occur after the finish of the other
• D. The finish of one task must occur after the start of the other

Answer: (B)

Finish-finish dependencies connect the completion moments of two activities. The requirement is that the finish of one task occurs before the finish of the other task. This means one task cannot be completed until the first has already finished, tying their finish times together. It’s different from other dependency types that link when activities start in relation to finishes or starts of others (for example, a task starting after another finishes, or two tasks starting in tandem). In finish-finish, the emphasis is on the order of completions rather than the starts.
