# DORA Metrics

The DORA framework is a set of metrics that help teams measure software delivery performance. The four key metrics are lead time for changes, deployment frequency, mean time to resolution (MTTR), and change failure rate.

The guides in this section help you use Cortex to complete work relating to DORA metrics.
