The Bolivia team can place parts manager and service technician in charge of failure-demand feedback. For the parts covered by failure-demand feedback, start with the parts catalog, package label, stock ledger, and issue record, then compare the electronic catalog, package label, and physical specification. Link failure-demand feedback to part number, applicable VIN, batch, and bin in the acceptance sheet rather than using only a model or project name. Before closing failure-demand feedback, review the corresponding import checklist. Quarantine the stock when parts related to failure-demand feedback are wrong or of unclear origin, and issue it to the workshop only after supersession is confirmed. If one document covers several service-parts operations matters, record a separate accepted or open decision for failure-demand feedback.
