DORA Benchmark Reference
| Metric | Elite | High | Medium | Low |
|---|---|---|---|---|
| Deployment Frequency | Multiple/day | 1/day – 1/week | 1/week – 1/month | Less than 1/month |
| Lead Time for Changes | < 1 hour | 1h – 1 day | 1 day – 1 week | > 1 month |
| Time to Restore (MTTR) | < 1 hour | < 1 day | 1 day – 1 week | > 6 months |
| Change Failure Rate | 0 – 5% | 5 – 10% | 10 – 15% | 16 – 30% |
Frequently Asked Questions
What are DORA metrics?▼
DORA (DevOps Research and Assessment) metrics are four key measures of software delivery performance: Deployment Frequency, Lead Time for Changes, Time to Restore Service (MTTR), and Change Failure Rate. They were identified through years of research by the DORA team at Google and are now industry-standard benchmarks.
What do the DORA performance tiers mean?▼
Elite: top 25% of performers. High: above median. Medium: below median. Low: bottom 25%. Elite performers deploy multiple times per day with lead times under 1 hour, MTTR under 1 hour, and change failure rates under 5%. Moving up one tier typically correlates with significant business outcome improvements.
What is MTTR and how is it calculated?▼
MTTR (Mean Time to Restore/Recover) measures the average time to restore service after an incident. Calculate it as: total downtime during incidents / number of incidents. The DORA Elite benchmark is under 1 hour; Low performers take over 6 months to recover from failures.
What is change failure rate?▼
Change failure rate (CFR) is the percentage of deployments that cause degraded service and require remediation (rollback, hotfix, or patch). DORA Elite benchmark is 0-5%. CFR = incidents caused by deployments / total deployments × 100. High CFR indicates insufficient testing or review processes.
How do I improve DORA metrics?▼
Deployment Frequency: invest in CI/CD automation and trunk-based development. Lead Time: shorten code review cycles and test execution times. MTTR: improve alerting, runbooks, and on-call processes. Change Failure Rate: add integration tests, feature flags, and progressive delivery (canary/blue-green deployments).
