They are dependency graphs.</p> <p>A deployment may need a database migration before the API starts, while static assets can build independently. A data pipeline may need two source extracts before a join can run. A build system may have several targets that become runnable as soon as their prerequisites finish.</p> <p>If you encode this work as one hand-written sequence, you hide the real constraint: <strong>which tasks depend on which other tasks</strong>. That makes the sequence harder to change and can prevent independent work from running concurrently.</p>
