# Provisioning Lead Time — Definition of Success > KPI: Provisioning Lead Time > Target: not a committed target (operational signal) **What this number means:** the time from intent received (run.started) to apply completed (run.completed). Measures how fast Nova provisions compliant environments. **How it's computed:** `run.completed_at − run.started_at` per run. **What "good" looks like:** minutes, not days. The reduction from days (human ops) to minutes (autonomous) is the velocity proof.
