Change Failure Rate (Commits based)
Connect your Git repository to calculate the ratio of fix-related commits among all merged pull requests commits.
Understand the Commits-Based Change Failure Rate
The commits-based CFR detects commits related to bug fixes using keyword search. The template identifies commits containing the keyword "fix" among all merged pull requests and calculates its ratio. You should amend the keyword (or list of keywords) to reflect your own naming convention.
What Is a Good Change Failure Rate?
A team or organization with a CFR between 0% and 15% is considered to be an elite performer based on DORA metrics. Medium performers observe a CFR rate from 15% to 45%, while low performers observe above a 45% rate.
How to Reduce Your Change Failure Rate
To keep your CFR between 0 and 15%, you should apply industry best practices such as:
- Adding linters and code analysis tools so developers can review their styling issues.
- Automating end-to-end testing (E2E).
- Documenting test edge cases, unstable flow, and incidents.
- Ensuring your test environment(s) reflects your production.
