Goal
Aggregate customer-side fault signals by model, firmware, batch, supplier and inspection standard, then drive CAPA, resale, refurbishment, disposal and knowledge updates.
Risk / exception
If a serial number cannot be linked or accountability evidence is insufficient, keep the case undecided and do not treat an initial warehouse inspection as final responsibility. Quarantine returns involving safety or data privacy first.
Close condition
Return events retain their sources; serials and batches are traceable; specialist decisions are approved; physical disposition has scan receipts; CAPA closes only after its observation window.
Next safe action
Choose one frequent return type and confirm serial-number coverage, quarantine rules and the CAPA observation window.

Comparison
Compare the same operating fields before choosing a direction.
Direction
Confirm the owner, authority, human gate, and readback rule.
Optimization
Define a baseline, target, owner, and observation window before claiming impact.
