What is a Predecessor? Definition and meaning
In project management, a predecessor is a task that precedes another task. The decisive factor here is the dependency between the two tasks, not the chronological order. A predecessor can also have several successors.
In order to identify a predecessor, you have to work out which task must already be completed. With the help of a Gantt chart or a network diagram, these can be shown graphically.

Predecessor vs predecessor in office: which one is meant
In everyday language, “predecessor” often refers to a person who held an office or a position before someone else, or to an earlier product model. In project management and in projectfacts, however, a predecessor means a task that precedes another task. What is meant here is therefore the planning dependency between tasks, not a person or a previous model.
