In a Finish-to-Finish (FF) relationship, what condition must be met?

In a Finish-to-Finish (FF) relationship, the primary condition that must be met is that the predecessor task must be completed before the successor task can be finished. This means that the completion of the successor is contingent upon the completion of the preceding task. However, it's important to note that the successor task can still be in progress while the predecessor task is finishing; they do not have to finish at the same time, but the completion of the predecessor directly influences when the successor can be completed.

This relationship is essential in project management for coordinating tasks that are dependent on one another. For example, in a project where one task is dependent on the results of another (like reviewing a report before it can be finalized), the Finish-to-Finish relationship ensures that the review (predecessor) must conclude before the finalizing of the report (successor) can be marked as complete. This dependency helps to maintain the integrity of the project timeline.
