Task dependencies are a foundational concept in project management, and refer to the relationship between multiple tasks in the context of a specific business activity. Specifically, task dependencies can be thought of as the way one task is affected (negatively or positively) by the progress of another related task. For example, if Task A must be completed before Task B can begin, then Task A is said to be dependent on Task B – this type of dependency is known as a finish-to-start relationship. By understanding how tasks relate to each other, organizations can build more efficient plans and processes that help reduce bottlenecks and delays.
