BUYER FIELD GUIDE / SUPPLIER CAPABILITY & PRODUCTION OPERATIONS
Root Cause Questions for Supplier Defects
Direct answer: Root-cause questions help a buyer connect the current defect reference, observation source, supplier explanation, corrective-action question, recheck point, and next buyer decision without assuming a cause.
What this guide helps clarify
A defect report may identify an observed product, package, process, or shipment problem. The buyer record should distinguish the observation, supplier response, evidence source, open question, and recheck route rather than treating an early explanation as the final answer.
Work through the current record in order
- Current product, order, inspection, sample, or shipment reference.
- Observed defect or reported issue with clear source context.
- Supplier explanation, response, image, report, or other evidence source.
- Open cause question, corrective action, recheck owner, and buyer decision.
