Wheel Hub Layered Process Audit: Buyer Evidence Review
Request the LPA program scope, responsible layers, competence, schedule and completion record, then sample process-specific questions tied to the current control plan, standard work, error-proofing or recent problems. For each audit, preserve process, station, shift, part or family scope, auditor, question revision, objective evidence, finding, immediate correction and escalation. Review overdue audits, repeat findings, closure evidence and effectiveness trends rather than accepting a completion percentage alone. Confirm whether a customer-specific LPA requirement actually applies before using its cadence or form.
