The DORA Metrics

Created by the DORA (DevOps Research and Assessment) Team at Google Cloud and published in the State of DevOps Report

Software Delivery Performance Metrics (DORA)

  • Deployment frequency (DF) (how often do you release to production?)
  • Lead time for changes (LTTC) (how long does it take from commit to production?)
  • Mean Time to restore (MTTR) (how long does it take to restore service after an unplanned outage?)
  • Change failure rate (CFR) (what percentage of changes require remediations/hotfixes?)


Using DORA metrics, teams can be ordered into low, medium, high and elite performers.
