DevOps Metrics
Measuring DevOps success requires the right metrics. The DORA metrics (from Google's State of DevOps reports) are the industry standard for evaluating team performance.
The Four DORA Metrics
┌───────────────────────────────────────────────────────┐
│ DORA Metrics │
├──────────────────────┬────────────────────────────────┤
│ Metric │ What it measures │
├──────────────────────┼────────────────────────────────┤
│ 1. Deployment │ How often you deploy │
│ Frequency │ (per day/week/month) │
├──────────────────────┼────────────────────────────────┤
│ 2. Lead Time for │ Time from code commit to │
│ Changes │ production deployment │
├──────────────────────┼────────────────────────────────┤
│ 3. Change Failure │ % of deployments causing │
│ Rate │ failures in production │
├──────────────────────┼────────────────────────────────┤
│ 4. Mean Time to │ Average time to restore │
│ Recovery (MTTR) │ service after failure │

Other Important Metrics
- Infrastructure Cost — Cloud spend per transaction
- Test Coverage — % of code covered by automated tests
- Uptime/SLA — Service availability percentage
- Developer Experience — Time from clone to first commit
- Security Vulnerabilities — Count and severity over time
