| USE CASE Inspect Cargo Delivery Status [subfunction] |
| =========================================================================== |
| A Delivery Inspector inspects and updates the delivery status of a cargo. |
| |
| If the cargo has been handled, the handling event data is used to derive the |
| delivery status. |

| |
| |
| Primary actor.. Delivery Inspector |
| Scope.......... Handling Monitoring System in shipping application |
| Preconditions.. Cargo has a route specification. |
| Trigger........ Delivery Inspector receives request to inspect the cargo delivery status. |
| |
| |
