DORA Metrics

Purpose

Compute the four DORA delivery-performance metrics (Deployment Frequency, Lead Time for Changes, Change Failure Rate, and Time to Restore Service) from local git history and the GitHub API. Classify each metric into Elite, High, Medium, or Low using thresholds from DORA's State of DevOps research, and surface the single weakest dimension as the next improvement target.

When to Use

• Engineering management retrospectives and quarterly reviews.
• Auditing whether agentic workflows (AI-assisted PRs, automated deploys) improve velocity and stability or quietly regress them.
• Feeding a tier signal into minister:release-health-gates.
