# Kaizen

> Six-step continuous-improvement write-ups: improvement potential → current
> method analysis → ideas → test plan → implementation → evaluation. One file
> per loop. Where a postmortem records how an incident was debugged, a kaizen
> records how a recurring cost was measured, attacked, and re-measured — and
> which standard changed so it stays fixed.
