售后问题反复出现，怎么从流程上根治？

Problem Statement: Carton packaging damaged during shipping (repeating 3 times in 6 months) **5 Why Analysis:** Why 1: Why do cartons get damaged? -> Because the cartons are crushed during loading and unloading Why 2: Why are cartons crushed during loading? -> Because workers stack cartons too high and unevenly Why 3: Why do workers stack cartons unevenly? -> Because there is no standard stacking guideline Why 4: Why is there no standard stacking guideline? -> Because the issue was never formally documented and communicated Why 5: Why was the issue never documented? -> Because there is no quality feedback loop between sales and production **Root Cause:** No formal quality feedback loop between sales and production **Corrective Action:** 1. Establish monthly quality review meeting (Sales + Production + QC) 2. Create standard container loading guidelines with diagrams 3. Require pre-shipment photography of container loading 4. Add packaging inspection point in QC checklist **Responsible:** Production Manager + QC Manager **Timeline:** Implement by next shipment cycle
