When delivery-delay communication crosses several steps, delivery specialist and service adviser should use one shared record. Close delivery-delay communication only when the pre-delivery checklist, dated vehicle photos, and signed handover record is complete and staff inspect the vehicle against the pre-delivery list and obtain customer confirmation of records and items. Link delivery-delay communication to VIN, customer, delivery date, and supplied items in the acceptance sheet rather than using only a model or project name. Before closing delivery-delay communication, review the corresponding import checklist. For unanswered items in the communication record, record the owner and closure date and do not treat the delivery item as finished until a reply is complete. This record covers only delivery-delay communication under customer delivery; other items require separate approval.
