Tool usage
PPAP ensures that suppliers have the ability to continuously produce qualified products during the production process.
FMEA (DFMEA/FMMEA) identifies potential failure modes in design and process, and prevents them in advance.
SPC (Statistical Process Control) monitors process stability and promptly detects abnormal fluctuations.
MSA (Measurement System Analysis) ensures the accuracy and reliability of inspection data.
The 8D problem-solving method is used to structurally solve major quality problems and achieve closed-loop management.
QMS systems (such as SAP QM, Oracle SQM) digitally manage supplier files, inspections, performance, issues, etc.

常见挑战与应对策略

挑战

应对策略

供应商隐瞒质量问题

建立“无责备报告文化”，鼓励主动上报；加强飞行检查。

小供应商能力不足

提供辅导；联合多家企业集中采购；考虑更换。

全球供应链复杂

建立本地备份供应商；加强数字化追溯；关注地缘政治风险。

成本压力导致质量妥协

推动价值工程（VE）而非单纯压价；建立长期合作关系。

变更管理失控

在质量协议中明确变更流程；使用PLM系统管理ECN。

Common challenges and coping strategies
Challenge response strategy
Suppliers conceal quality issues and establish a 'no blame reporting culture' to encourage proactive reporting; Strengthen flight inspections.
Insufficient ability of small suppliers to provide coaching; Joint procurement with multiple enterprises; Consider replacement.
Establishing local backup suppliers for complex global supply chains; Strengthen digital traceability; Pay attention to geopolitical risks.
Cost pressure leads to quality compromise, driving value engineering (VE) rather than simply price cutting; Establish long-term cooperative relationships.
Change management is out of control and the change process is clearly defined in the quality agreement; Use PLM system to manage ECN.

供应商质量管理 = 流程 + 工具 + 人 + 文化

流程化：建立从准入到淘汰的完整流程。
数据驱动：用KPI量化绩效，科学决策。
合作共赢：从“管控”转向“赋能”，与优质供应商建立战略伙伴关系。
预防为主：通过FMEA、PPAP等工具，将问题消灭在萌芽状态。
✅ 最终目标：让供应商“第一次就把事情做对”，实现“零缺陷”交付。

Supplier Quality Management=Process+Tools+People+Culture

Process oriented: Establish a complete process from admission to elimination.
Data driven: Quantify performance with KPIs and make scientific decisions.
Win win cooperation: shifting from "control" to "empowerment" and establishing strategic partnerships with high-quality suppliers.
Prevention oriented: Eliminate problems in their early stages through tools such as FMEA and PPAP.
✅  The ultimate goal is to enable suppliers to "get things right the first time" and achieve "zero defect" delivery.
