## Definition
|
||
|
||
CAPA (Corrective and Preventive Action,纠正和预防措施) 是 Emergency Change 事后必须执行的流程,用于从事故中提取根本原因并预防同类问题再次发生。CAPA 通常与 Post-mortem 回顾结合使用。
|
||
|
||
## Components
|
||
|
||
### Corrective Action(纠正措施)
|
||
- 修复当前事故的直接措施
|
||
- 目标是恢复服务到期望状态
|
||
- 通常在 Emergency Change 执行阶段完成
|
||
|
||
### Preventive Action(预防措施)
|
||
- 防止同类问题再次发生的长期措施
|
||
- 目标是消除根本原因
|
||
- 通常在 Post-mortem 分析后制定
|
||
|
||

||
## Process
|
||
|
||
1. **Incident Review**:回顾事故经过
|
||
2. **Root Cause Analysis**:识别根本原因
|
||
3. **Corrective Action**:执行即时修复
|
||
4. **Preventive Action**:制定长期预防措施
|
||
5. **Follow-up**:跟踪措施执行情况
