DORA (DevOps Research and Assessment) Core Model for measuring and improving software delivery performance. Use this skill to assess team performance tier, identify capability gaps, and connect delivery metrics to product release strategy.
npx skill4agent add kinhluan/skills dora-core| Metric | What it measures |
|---|---|
| Deployment Frequency (DF) | How often code is deployed to production |
| Lead Time for Changes (LT) | Time from code commit to running in production |
| Change Failure Rate (CFR) | % of deployments causing a production incident |
| Time to Restore (MTTR) | Time to recover from a production failure |
| Tier | Deployment Frequency | Lead Time | Change Failure Rate | MTTR |
|---|---|---|---|---|
| Elite | On-demand (multiple/day) | < 1 hour | 0–5% | < 1 hour |
| High | 1/day – 1/week | 1 day – 1 week | 6–15% | < 1 day |
| Medium | 1/week – 1/month | 1 week – 1 month | 16–30% | 1 day – 1 week |
| Low | 1/month – 1/6 months | 1 month – 6 months | 16–30% | > 1 week |
| Capability | Impact | Integration |
|---|---|---|
| Loosely Coupled Architecture | #1 predictor of high DF | |
| Trunk-Based Development | Reduces integration debt | Short-lived branches, feature flags |
| Continuous Integration | Reduces LT and CFR | Automated test on every commit |
| Test Automation | Reduces CFR | Unit + integration tests in CI |
| Deployment Automation | Reduces LT | One-click or auto deploy to prod |
| Shifting Left on Security | Reduces CFR | Security checks in CI, not post-deploy |
| Monitoring & Observability | Reduces MTTR | Metrics, logs, traces in production |
| Database Change Management | Reduces CFR | Schema migrations versioned and automated |
| Capability | Impact |
|---|---|
| Working in Small Batches | Directly reduces LT and CFR |
| Streamlining Change Approval | Manual approval gates are the #1 LT killer |
| Team Experimentation | Faster learning → better product decisions |
| Customer Feedback | Shorter feedback loop → less wasted work |
| Capability | Impact |
|---|---|
| Generative Culture (Westrum) | High trust, blameless postmortems → faster MTTR |
| Psychological Safety | Teams that can surface problems fix them faster |
| Learning Culture | Continuous improvement on all 4 metrics |
git commitdiffusion-release-trackingcollaborative-engineering-agent| DORA Metric | CEA Practice |
|---|---|
| Lead Time ↓ | Atomic PRs (<200 lines), trunk-based dev reduces integration bottleneck |
| CFR ↓ | Dialectical Review Engine (DRE) catches issues before merge |
| MTTR ↓ | Automated fix-branch workflow, observability tooling |
c4-modelddd-corebusiness-product-leadership| DORA Tier | Product Strategy Implication |
|---|---|
| Elite | Deploy on-demand → rapid MVP validation, tight Rogers feedback loop |
| High | Weekly deploys → manageable Early Adopter gate iteration |
| Medium | Monthly deploys → must plan Rogers gate windows months in advance |
| Low | Cannot run agile product strategy — delivery is the bottleneck |
