Change Failure Rate (CFR)

A DORA metric measuring the percentage of deployments that cause a failure in production requiring remediation.

Definition

Failures include incidents, rollbacks, hotfixes, or degraded service caused by a change. It balances speed metrics by showing whether faster delivery is reducing quality.

Example

If 3 of 60 deployments in a month required rollback, the change failure rate is 5%.

Exam tip

CFR is a stability metric; improving tests and progressive delivery lowers it.
