## 定义
DORADevOps Research and Assessment四指标是衡量 DevOps 效能的核心量化框架,被 Google 团队研究成果验证。
## 四个核心指标
1. **部署频率Deployment Frequency**:组织能多频繁地向用户交付新功能
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**:部署失败的百分比
4. **平均恢复时间Mean Time to Recovery, MTTR**:从故障恢复到服务正常的时间
## 精英团队特征
- 部署频率:每天多次到每月多次
- 变更前置时间:少于一天到一周
- 变更失败率0-15%
- 平均恢复时间:少于一小时
## 在 Wiki 中的角色
- 是 [[DevOps Culture and Transformation]] 和 [[Cloud-DevOp-Maturity-Guideline]] 的核心评估框架
- 关联概念:[[Kaizen]](持续改进)、[[CI/CD Pipelines]]
