the argument about whether the team was fast stopped once four numbers were on the wall.
DORA metrics
Also calledfour key metrics, accelerate metrics
Four measures of delivery performance from the DORA research: deployment frequency, lead time for changes, change failure rate and time to restore service. Their power is the pairing — two speed measures against two stability measures — which kills the assumption that going faster must mean breaking more. They are diagnostic rather than a target, and turning them into individual or team goals is the fastest way to make them useless.
