What types of dependencies between tasks?

Main types of dependencies between tasks in project management:

• Finish-to-Start (FS) — the most common dependency, where the next task starts only after the previous one is completed.
• Start-to-Start (SS) — tasks can start simultaneously or with a certain delay, but one cannot start before the other.
• Finish-to-Finish (FF) — tasks must finish at the same time or with a certain dependency, one cannot finish before the other.
• Start-to-Finish (SF) — a rare dependency where a task cannot finish before another starts.

These dependencies help in building schedules and managing the sequence of tasks in a project.
