### Key metrics definitions

This Four Keys project defines the key metrics as follows:

- [[Deployment Frequency]]
  - How frequently a team successfully releases to production, e.g., daily, weekly, monthly, yearly.

- [[Lead Time for Changes]]
  - The median amount of time for a commit to be deployed into production.

- [[Time to Restore Services]]
  - For a failure, the median amount of time between the deployment which caused the failure and the remediation. The remediation is measured by closing an associated bug / incident report.

- [[Change Fail Rate]]
  - The number of failure per the number of deployment. For example, if there are four deployments in a day and one causes a failure, that is a 25% change failure rate.
