Silent video with on-screen text. The transcript below repeats every screen and describes what it shows.

  1. 0:00–0:06

    Scope one order • Propose manual dispatch. • Illustrative example • One restaurant • Order A

    Illustrative example: Order A enters the bounded scope of One restaurant. The restaurant artwork also reads One restaurant. This proposes manual dispatch and creates no real order.

  2. 0:06–0:12

    Name the dispatcher • Give the request a clear owner. • Illustrative example • One restaurant • Dispatcher • Order A

    Order A leaves the restaurant scope and moves into the Dispatcher responsibility area. The headset illustration also reads Dispatcher. The same request now has a named operational owner.

  3. 0:12–0:18

    Define courier acceptance • Specify how the courier responds. • Illustrative example • Dispatcher • Courier • Assign • Pending • Order A

    The Dispatcher initiates Assign and sends Order A towards the Courier. Pending appears after the request arrives. Dispatcher and Courier are also visible in the actor illustrations. The courier has not accepted, and no delivery is shown.

  4. 0:18–0:24

    Write the failure path • Return the decision to the dispatcher. • Illustrative example • Dispatcher • Courier • Unavailable • Order A

    Unavailable appears beside the Courier before Order A returns to its original Dispatcher. The dispatcher illustration also reads Dispatcher. The return assigns responsibility for the next decision; it does not perform an automatic reassignment.

  5. 0:24–0:30

    Include the fallback in the quote • Agree the procedure before building. • Illustrative example • Procedure to agree • Dispatcher • Fallback rule • Order A

    The Dispatcher places Order A in a written scope and adds a Fallback rule in a separate compartment. Procedure to agree remains visible at the end. No fallback has been approved, priced or implemented.

A silent illustrative order follows a manual assignment and returns to its dispatcher when no courier accepts, so the fallback can be included in the scope.
