# 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

#### What a Good CFR Looks Like

| Elite | High     | Medium    | Low  |
| ----- | -------- | --------- | ---- |
| <5%   | >5%-<10% | >10%-<15% | >15% |
