供应链平台与生态系统

没有一个系统能独立完成供应链的全部工作——ERP、WMS、TMS、需求预测、供应商门户必须连接成生态，数据才能真正流动。

行动清单

• [ ] 绘制当前系统集成现状图（哪些系统有 API 集成，哪些靠人工导数据）
• [ ] 识别最高优先级的集成点：ERP ↔ WMS ↔ TMS 数据流是否实时可见
• [ ] 对计划引入的新系统进行选型评估（用上方评估框架，至少对比 3 个方案）
• [ ] 优先选择有完善 API 和 Webhook 的系统，避免只能手工导出导入的"信息孤岛"
• [ ] 建立数据字典：统一各系统之间的字段映射关系（物料编码、供应商编码等）
• [ ] 设置集成监控告警：接口调用失败、数据延迟超阈值时发送通知
