The percentage of code changes that require hotfixes or other remediation after production is ________
- Deployment Frequency
- Lead Time
- Change Failure Rate
- Time to Restore Service
Answer
Change Failure Rate
Change failure rate is the ratio of code changes that need hotfixes or other remediation after production. It doesn’t account for failures caught by testing and fixed before code is deployed.
Interestingly enough, elite, high, and medium performers typically fail to make changes at a rate of 0–15%, whereas low performers fail to make changes at a rate of 40–65%.
The gold standard is to have an automated, consistent, and reliable development process. The chances of a high change failure rate are high without an automatic and established method as teams will have to make many small changes.
The key is acting on failures as soon as possible and gleaning information from failures to improve future workflows.
