Late unloading can result from vehicle delay or an internal queue. Assigning all elapsed time to the carrier hides yard constraints.
What the quote needs to include
Record the agreed slot, arrival, dock call and release. Define early-arrival handling and verify what captured timestamps actually represent.
These times do not automatically determine penalties or contractual responsibilities.
Define who records each event: gate staff, booking coordinators and unloading teams may use different tools. When release is entered later, entry time does not automatically replace event time. Retain both where available. The supplier should demonstrate detection of duplicates and contradictory sequences without guessing corrections. Include interrupted unloading and a shipment handled at several docks in acceptance. Operations must explain these cases before comparing shifts. Calendar alerts may resolve slot organization; a BI project becomes relevant for historical investigation and recurring causes. Confirm the comparison population so cancelled bookings and vehicles that never arrived are not silently mixed with completed handling activities.
Specific acceptance criteria
- Keep original slots after schedule changes.
- Separate yard waiting from actual unloading.
- Route missing events to operational review.
The exception that determines acceptance
A truck arrives early and waits beyond the agreed start. Testing must separate early arrival, subsequent waiting and actual unloading operations.
