What is a Change failure rate?

The change failure rate is the percentage of code changes that lead to failures in production. It’s code that needs to be fixed or called back after it has been deployed. Also, this metric isn’t concerned with failures that happen before deployment.

  3. Adding automation to the deployment process.
  4. Ensuring that the CI/CD process is as efficient as possible.

What is an acceptable failure rate for software?

You should strive for a 0% failure rate within the constraints of the Requirements. Sometimes a client will accept a program with a low failure rate in some situations if they feel it does not matter enough to warrant the extra cost to fix the problem.

What is lead time for changes?

Lead Time for Changes—The amount of time it takes a commit to get into production. Change Failure Rate—The percentage of deployments causing a failure in production. Time to Restore Service—How long it takes an organization to recover from a failure in production.
