Is finish to finish or start to start more common?

The most common dependency relationship is a finish-to-start relationship. Task P (predecessor) must be finished before task S (successor) can start. The least common relationship is the start-to-finish relationship.

What does finish to finish mean in scheduling?

Understanding the dependency between tasks is critical for project scheduling and execution. Finish-to-finish (FF) means that one task can only be completed after the other task has been completed. In other words: a successor activity can only finish after its predecessor has been completed.

What is the difference between finish to start and start to finish?

Finish to Start (FS)—The predecessor ends before the successor can begin. Start to Start (SS)—The predecessor begins before the successor can begin. Finish to Finish (FF)—The predecessor ends before the successor can end. Start to Finish (SF)—The predecessor begins before the successor can end.

What does finish to finish mean in Microsoft project?

Finish-to-finish (FF) Indicates that the finish date of the predecessor task determines the finish date of the successor task. For example, if you have rented a lab for editing the scenes, the editing task must be complete when the lab rental ends.

Is finish to finish common?

Finish-to-finish (FF) is not very common in network diagrams. This project management dependency is used in activity-on-node diagrams but not used in the activity-on-arrow diagram.

When should you start and end a relationship?

Start-to-finish relationships are usually found in scheduling scenarios where there is some sort of handover between two tasks. Start-to-finish is the opposite of the finish-to-finish dependency. In a finish-to-finish relationship, the next task can only be finished once the predecessor task is 100% complete.

What is Finish to Finish activity example?

Finish-to-Finish (FF)

For example, “Fracking cannot finish until pressure testing is complete” “Electrical work cannot finish until drywalling is complete.” “Design work cannot finish until environmental studies are complete”

What is Finish to Finish dependency?

A FF or Finish to Finish dependency says that the successor task can’t finish unless the predecessor task is also finished. They don’t need to complete together.

How do finish to finish relationships work?

According to the PMBOK Guide, “Finish to Finish is a Logical Relationship in which a Successor Activity cannot finish until a Predecessor Activity has finished.” In simpler words, the end of the successor activity depends on when the predecessor is done.

How do I finish a project in MS Project?

Because Finish-to-Start is the default link type, Microsoft Project will assume that you want a Finish-to-Start link, even if you don’t specify “FS” in your shorthand.
Here is the shorthand syntax for the four different dependency types:

  1. Finish-to-Start: FS.
  2. Finish-to-Finish: FF.
  3. Start-to-Start: SS.
  4. Start-to-Finish: SF.

What does FS and FF mean in MS Project?

Each predecessor task is represented by its task ID number, which may be followed by a dependency type and the lead or lag time. The dependency types for predecessors are FS (finish-to-start), FF (finish-to-finish), SS (start-to-start), and SF (start-to-finish). To enter lead time, type a negative number.

How do I add a finish-to-start in Microsoft project?

Project creates a simple finish-to-start task link by default, which means the first task (the predecessor) needs to finish before the second task (the successor) can start.
Link tasks

  1. Choose View > Gantt Chart.
  2. Hold down Ctrl and select the two tasks you want to link (in the Task Name column).
  3. Choose Task > Link Tasks.

What is finish-to-start lag?

Lag. The amount of time whereby the successor activity can be advanced with respect to a predecessor activity. Here is an example of a lag: In a finish-to-start dependency with a ten-day lag, the successor activity cannot start until ten days after the predecessor activity has finished.

What is finish start dependency?

A Finish-to-Start (FS) dependency is perhaps the most common dependency type that you will come across in projects. This is due to the fact that this ‘type’ means a successor (second task) cannot begin until its predecessor (first task) is complete, which is the most common scenario in projects.
