dev.test-deploy-freq Calculator
Calculates deployment frequency, batch size per deploy, and the mean change fail rate from deployment logs in a software testing and quality assurance context. DORA elite performers deploy multiple times per day — deploy frequency correlates inversely with deployment risk when combined with automated testing and rollback capability.
Inputs
Deploys
Reference formula or conversion factor shown for context.
Team
Reference formula or conversion factor shown for context.
Success
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
deploys/day
Deployment frequency — a DORA metric. Elite engineering teams deploy multiple times per day. Higher frequency enables faster feedback and smaller rollbacks.
per developer
Reference formula or conversion factor shown for context.
failed deploys
Number of deployments that resulted in a rollback or incident. A key input to the DORA change failure rate metric.
DORA
DORA (DevOps Research and Assessment) performance classification — Elite, High, Medium, or Low — based on the four key DevOps metrics: deployment frequency, lead time, MTTR, and change failure rate.
