Fleet KPI — Mechanical Availability
Mechanical Availability for equipment fleet management decisions.
Availability is the KPI that converts maintenance into operations language: a 90% machine gives you 9 of every 10 planned hours. The replacement signal isn't one bad month — it's the TREND across six, which no repair invoice shows but this simple ratio tracks.
