DORA Metrics

Four key software delivery metrics from the DevOps Research and Assessment program: deployment frequency, lead time, change failure rate, and recovery time.

Definition

DORA research links these metrics to organizational performance. Throughput is measured by deployment frequency and lead time for changes; stability by change failure rate and failed deployment recovery time (formerly time to restore service). Later reports added reliability and rework rate as further measures.

Example

An elite team deploys on demand, has lead time under a day, and recovers from failed deployments in under an hour.

Exam tip

Know which metrics measure speed versus stability; Google's DevOps exam and AZ-400 both reference DORA.
