DORA metrics are standardized key performance indicators developed by Google's DevOps Research and Assessment team to measure software delivery speed and stability. Engineering teams use them to identify bottlenecks, balance velocity with quality, and benchmark their delivery maturity against industry standards.
The Core DORA Metrics
The four primary metrics are divided into two categories:
Velocity & Throughput
- Deployment Frequency (DF): How often code is successfully released to production (e.g., multiple times a day vs. once a month).
- Lead Time for Changes (LT): The time it takes for a commit to travel from the beginning of the development cycle to production deployment.
Stability & Reliability
- Change Failure Rate (CFR): The percentage of deployments that cause a production failure and require immediate remediation.
- Mean Time to Recover (MTTR): The average time it takes an organization to restore service after a production failure or incident.
