What defines a Finish-to-Start (FS) relationship?

A Finish-to-Start (FS) relationship is defined by the need for the predecessor activity to be fully completed before the successor activity can commence. This means that for a task to move forward, the prior task must not only be underway but must be finished entirely. This relationship reflects a sequential dependency, which is essential in project management to maintain order and ensure that tasks are performed in the correct sequence.

Understanding this type of dependency is crucial in planning and scheduling project activities. For instance, if you are building a home, the foundation (predecessor) must be poured and completely set before moving on to the framing (successor). If the framing were to begin before the foundation is set, it could lead to structural issues or delays.

In contrast, other types of relationships mentioned suggest different dependencies that would not fit the definition of Finish-to-Start. The other options imply either overlapping task timings or conditions that contradict the foundational concept of task completion before the initiation of successor tasks.
