- The DORA metrics are used to understand and monitor team performance in terms of maintainability, reliability, and efficiency.
- These metrics are second-order data derived from first-order data such as deployment timestamps, feature lists, and failure events.
- Deployment frequency can be tracked by tagging deployed commits in Git or using CI tools to record deployment timestamps.
- Mean time to deployment requires tracking feature lifecycle through Git history with labeled commits and release tags.
- Change failure rate needs manual identification of failures and associating them with the causing deployment, using bug-tracking systems.
- Time to restore service is obtained from monitoring systems by recording failure start and restoration times.
- Automated data extraction from version control, bug tracking, and monitoring systems is essential to avoid manual overhead.
- Clear upfront definitions of terms like 'failure', 'deployment', and 'feature' are necessary for meaningful data analysis.
