What are predecessors?

Predecessors are Schedule Tasks that must start or finish before another Schedule Task can start or finish. When a Schedule Task is set as a predecessor for another task, a predecessor relationship is created between the two tasks. A predecessor relationship acts as a link between the tasks, making one task dependent upon the other so that each task may begin as soon as possible or progress in the ideal order. Any changes to a predecessor task will affect other linked tasks—also referred to as successor tasks.
