Change Failure Rate - CI/CD Glossary Definition
Change failure rate is a DORA metric: the percentage of deployments that cause a failure in production requiring remediation (a rollback, hotfix, or patch). Elite teams keep it between 0 and 15 percent.
Why it matters
A low change failure rate reflects effective testing and gating before release. It is reduced by strong CI checks, canary deployments, and the ability to roll back quickly.
