Change Failure Rate

Change failure rate gives the percentage of deployments which result in degraded service and subsequently require remediation (hotfix, rollback, patch, etc).

This metric is configurable under app.hatica.io/settings/dora (opens in a new tab) and currently supports either a PR label Regex or a PR title Regex to recognise PRs containing the fix for a recent failure

App inputs to this metric:

CI-CD tools

Range points and what they mean:

The DORA performance grades for Change failure rate are:

1. Elite - Between 0-15%

2. High - Between 16-30%

3. Medium - Between 31-45%

4. Low - Between 46-60%

Use cases:

1. Understand how likely a release is going to break and plan releases accordingly

2. Identify projects, PRs, etc that have repeatedly resulted in Failures and conduct RCAs
