Types of dependencies
From apppm
In a traditional Gantt scheduling the link between activities or tasks are called dependencies, there are 4 types:
- Finish-Start (FS)
- Finish-Finish (FF)
- Start-Start (SS)
- Start-Finish (SF)
By defining the dependency between Start and Finish dates you are defining the type of link between activities or tasks. For example, the "Contact caterers" task must finish before the start of the "Determine menus" task.
| Task dependency | Description |
| Finish-Start (FS) | Task (B) cannot start until task (A) finishes |
| Finish-Finish (FF) | Task (B) cannot finish until task (A) finishes |
| Start-Start (SS) | Task (B) cannot start until task (A) starts |
| Start-Finish (SF) | Task (B) cannot finish until task (A) starts |
