Change Failure Rate - CI/CD Glossary Definition
Change failure rate is the share of deployments that break production and need a fix or rollback.
Change failure rate is the percentage of deployments that cause a failure in production requiring remediation (a hotfix, rollback, or patch). It is one of the four DORA metrics.
Why it matters
A low change failure rate paired with high deployment frequency signals that automated testing and CI gates are catching defects before release.
