In project management, what does the term 'dependency' refer to?

In project management, the term 'dependency' specifically refers to a relationship between tasks where one task relies on the completion of another before it can begin. This relationship is crucial to project scheduling and planning, as it helps project managers understand the sequence of activities necessary for project completion. Dependencies can significantly impact the timeline, as delays in one task can ripple through to others that depend on it.

Recognizing dependencies allows project managers to create a more effective and realistic project schedule. For example, if Task B cannot commence until Task A has been completed, understanding this dependency helps ensure that resources are aligned, and timelines are adjusted accordingly to avoid bottlenecks. This understanding is pivotal for efficient project execution and management.
