业务连续性规划 BCP

应急预案解决"发生了什么",而 BCP 解决"能不能继续运营"——两者的区别在于,BCP 提前量化了每种中断场景对业务的影响,并为每种场景准备了可执行的恢复路径。

BCP 框架(ISO 22301)

BCP 恢复策略矩阵

中断场景 影响 恢复策略 RTO 目标
主仓库火灾 仓储能力归零 启用备用仓库(预签协议) 48 小时
ERP 系统崩溃 订单处理停止 切换灾备系统 4 小时
核心供应商断供 生产停线 激活备选供应商 7–14 天
主要物流商停运 发货停止 切换备用物流商 24 小时
数据泄露 合规/声誉风险 隔离系统,启动应急响应 即时
关键人员突然离职 知识断层 启动接班人计划,文档化操作 1–3 天
