Change Failure Rate
The percentage of deployments that result in a production incident
Definition: Total incidents ÷ Total deployments × 100%
Change Failure Rate (CFR) tracks the stability of your deployments. It answers: "How often do changes make it to production without causing an incident?"
A lower CFR indicates more reliable deployments; a higher CFR suggests deployments frequently trigger production issues that need immediate incident response.
How Data Is Collected
Hivel calculates CFR by connecting to your incident management platform through the Incident API:
Retrieves incidents from your incident management tool
Identifies deployment frequency from your CI/CD system
Correlates incidents with the deployments that occurred on the incident start date
Calculates the percentage in real-time
