Change Failure Rate
In plain terms
The percentage of deployments that cause a failure.
Going deeper
Change failure rate tracks how often releases break production and need remediation, indicating delivery quality. Lower is better.
Under the hood
A DORA metric balancing speed; high frequency only helps if failures stay low.
Examples
DORA metrics, deploy reliability, incident rate, release quality.
Think of it like...
Like the fraction of dishes sent back to the kitchen, you want it small even when serving fast.
