dev.infra-recovery-time Calculator
Calculates Mean Time to Recover (MTTR) from incident severity, detection time, and remediation time in a cloud infrastructure and DevOps context. DORA elite MTTR is less than 1 hour — MTTR is the primary signal of incident response capability and is reduced by runbooks, automated rollback, and observability.
Inputs
Incidents
Reference formula or conversion factor shown for context.
Total Min
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Sla

Results
MTTR
MTTR (mean time to restore) — the average time to recover from a failure. A key DORA metric. Elite teams restore service in under one hour.
vs target
The current value compared to the goal. A positive number means the target is exceeded; negative means it is not yet met.
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.
