## Definition
DORADevOps Research & Assessment指标是用于衡量组织 DevOps 性能和交付能力的关键度量标准。
## Four Key Metrics
1. **部署频率Deployment Frequency**:代码部署到生产的频率
2. **变更前置时间Lead Time for Changes**:从代码提交到生产部署的时间
3. **变更失败率Change Failure Rate**:部署导致生产环境失败的比例
4. **平均恢复时间MTTR**Mean Time to Recovery服务从故障中恢复的平均时间
## Significance
- DORA 指标是评估 DevOps 成熟度的核心量化工具
- 高绩效组织通常部署频率高、前置时间短、变更失败率低、MTTR 短
