For bulk orders, do not review cross-factory supply by sampling only one vehicle or one document. Use stratified sampling by model, lot, and exception risk, and record every check using factory order numbers, production-scheduling milestones, vehicle allocation schedules, and change records. If the same deviation recurs, expand sampling or suspend release to avoid verbal inventory or production promises that cannot be tied to this vehicle lot. The decision boundary is linking payment release to verifiable vehicle progress.
