Score the four DORA delivery metrics and assign a performance tier.
DORA splits into throughput and stability, and the research finding is that these improve together rather than trading off. Teams deploying more often generally also fail less and recover faster. The counterintuitive result is that slowing down to be careful makes stability worse, because larger batches are harder to diagnose when they fail.

Each metric is banded into Elite, High, Medium or Low, then averaged

This calculator takes 4 inputs: Deployments per week, Lead time for changes, Change failure rate, Time to restore service. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
