Nachbesserungskosten durch fehlerhafte Flow-Down von kritischen Fertigungsmerkmalen
Definition
Key characteristics (critical dimensions, material properties, surface finish, heat treat parameters) and special processes (welding, plating, NDT) must be explicitly communicated to sub-tier suppliers. Manual flow-down processes omit critical requirements or use ambiguous language. Sub-suppliers manufacture parts that fail qualification testing or customer inspection, triggering rework, scrap charges, and potential warranty liability.
Key Findings
- Financial Impact: 2–10% of component cost per rework cycle; 5–20 rework events/year per supplier = €50,000–€500,000 annual scrap/rework cost; customer compensation: €10,000–€100,000 per incident (typical for aerospace)
- Frequency: 5–20 quality events per year per supplier (industry data suggests 3–8% defect rates in manual flow-down processes)
- Root Cause: Inconsistent documentation of key characteristics in purchase orders; unclear specification of critical process parameters; no automated validation that PO requirements match customer contract specifications
