DORA metrics of delivery performance

DORA is DevOps Research and Assessment team at Google Cloud. Four DORA metrics are:

  • Deployment frequency - how often organization deploys code for a particular application or service.
  • Lead time for changes - how much time it takes from committed to be running in production.
  • Time to restore service - how much time it takes to restore the service when incident or defect impacts users.
  • Change failure rate - what percentage of changes to production or released to users result in degraded service and subsequently require remediation.

The four metrics are about throughput and stability

Throughput is measured by:

  • Lead time for code changes
  • Deployment frequency

Stability is measured by:

  • Time to restore a service
  • Change failure rate
