How It Works
MTTHI (mean time to human intervention)
The average time between an automated or AI agent system hitting a problem and a person stepping in to handle it. Teams running agents in production track it to see how quickly failures reach someone who can act; a lower number means problems get human attention faster.
Origin · no single documented coiner
Modeled on older reliability metrics such as MTTR (mean time to repair) and MTBF (mean time between failures). It appears in AI-agent operations and escalation-design writing from 2025–2026. No single documented coiner and no standard definition.
