supplier performance management

**Supplier performance management** is the **continuous measurement and improvement of supplier quality, delivery, cost, and technical capability** - it ensures vendor performance supports fab uptime, yield targets, and long-term roadmap needs. **What Is Supplier performance management?** - **Definition**: Governance process that evaluates supplier outcomes against operational and strategic requirements. - **Scorecard Dimensions**: Incoming quality, on-time delivery, responsiveness, cost competitiveness, and engineering support. - **Data Inputs**: Defect rates, corrective-action closure time, lead-time adherence, and service reliability. - **Governance Cycle**: Regular reviews with escalation paths for underperforming suppliers. **Why Supplier performance management Matters** - **Quality Assurance**: Weak supplier quality can introduce recurrent tool failures and process variation. - **Downtime Risk Reduction**: Delivery misses on critical parts extend maintenance outages. - **Cost Stability**: Structured supplier oversight controls hidden costs from poor reliability. - **Roadmap Alignment**: Strategic suppliers must support future node and equipment requirements. - **Risk Diversification**: Visibility enables second-source planning before disruptions occur. **How It Is Used in Practice** - **KPI Framework**: Maintain standardized supplier scorecards with weighted business-critical metrics. - **Corrective Actions**: Issue SCAR processes for recurring defects with verified containment and prevention. - **Business Reviews**: Hold monthly or quarterly performance reviews tied to sourcing decisions. Supplier performance management is **a direct lever for fab reliability and procurement resilience** - disciplined vendor governance reduces defects, delays, and supply-chain volatility.
