Finish to Start (FS) task dependency is a type of logical relationship between two activities in project management. It means that the start of the successor activity depends on the completion of the predecessor activity. This type of dependency is also known as “finish-start” or “finish-begin”.
In other words, the successor activity cannot begin until the predecessor activity has been completed. This type of dependency is one of the most commonly used dependencies in project management and it is often used when creating a project schedule.
The main advantage of using finish to start task dependency is that it allows for better planning and scheduling of tasks. By having a clear understanding of which tasks must be completed before others can begin, project managers can create more accurate timelines and schedules.
Another advantage of this type of task dependency is that it helps to ensure that all tasks are completed in the correct order. By ensuring that each task is completed before the next one begins, project managers can avoid costly delays and rework due to incorrect sequencing.
One potential disadvantage of using finish to start task dependency is that it can lead to delays if there are any unexpected issues with completing the predecessor activity. If an issue arises with completing the predecessor activity, then all subsequent activities will be delayed until it is resolved.
Another potential disadvantage is that this type of task dependency does not allow for any overlap between activities. Since each activity must be completed before the next one can begin, there is no room for overlapping activities which could potentially reduce overall project duration.
