DORA Metrics

Development Frequency - how often an organization successfully releases production 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

These metrics were developed by Google1

A fifth metric was added reliability which encompasses availability, latency, performance and scalability2.

Alternate views

Some have argued that the only metric that matters is Lead Time for Changes, since speed is all that matters. Tracking change failure rate creates fear and caution in the organization. Rather, accept failures and focus on mean time to repair3.
