Fehlende Traceability zwischen Schweißverfahren und Fehlerquoten verursacht suboptimale Supplier-Entscheidungen
Definition
Weld material costs (consumables, gases, services) typically 5–10% of product cost for railroad equipment. Procurement buys on price; quality/engineering lacks veto power. Missing data linkage: 'Supplier X wire + Procedure Y = 2% defect rate' vs. 'Supplier Z wire + Procedure Y = 0.5% defect rate.' When defects occur, rework labor (€100–€500/hour in Germany) and scrap (€500–€5,000/component) offset material savings. No decision audit trail → same supplier reselected next year despite history.
Key Findings
- Financial Impact: €40,000–€120,000 annual rework/scrap cost attributable to suboptimal supplier selection; 50–150 hours/year re-qualification cycles due to supplier changes; 0.5–2% defect rate variance between suppliers (€200,000–€1,000,000 revenue impact on €50M annual sales); 3–6 month supplier consolidation delay when defects finally trigger remediation.
- Frequency: Per quarterly procurement cycle; Triggered on quality incident or supplier audit failure.
- Root Cause: Weld procedure data (material supplier, alloy grade, defect history) stored in quality system (Minitab, JMP) disconnected from procurement system (SAP) and cost accounting (DATEV/GnuCash). Procurement only sees unit cost, not total cost of ownership (TCO) including rework. No automated alerts when supplier defect rate exceeds threshold; supplier performance reviews conducted manually, months after incidents.
