DORA Metrics Definitions

platform dora metrics deployment

Four DORA metrics as defined for the Demo Corp deployment automation platform.

Metrics

1. Deployment Frequency — count of successful prod deploys per service per day/week/month
2. Lead Time for Changes — median time from PR merge to production deploy
3. Change Failure Rate — % of deploys that trigger a rollback within 30 minutes
4. Mean Time to Recovery — median time from rollback to next successful deploy

Implementation

• API endpoint: GET /api/metrics/dora?service=all&period=30d
• Query must run in <500ms for 90-day window
• Denormalize Jira ticket number into deployments table at write time (webhook-router writes during GitHub push event processing)
• Current correlation is a 4-hop lookup: commit → PR → branch → ticket number — too slow for reads

Schema Change

• Deployments table migration adds jira_ticket_key column
• May require backfilling existing records
