Overall Equipment Effectiveness (OEE)
Availability × Performance × Quality — the single most-used measure of how productively an asset really runs.
Mean Time Between Failures (MTBF)
Average operating time between failures of a repairable asset. The higher it climbs, the more reliable the machine.
Mean Time to Repair (MTTR)
Average time to restore a failed asset — from breakdown to running again. Lower is better.
Equipment Availability
Share of scheduled time an asset is actually available to run. The headline uptime number leadership cares about.
Mean Time to Failure (MTTF)
Average life of a non-repairable item (e.g. a bearing, a smart multi-sensor device) before it fails. Key for spares and lifecycle planning.
Failure Rate (λ)
How often an asset fails per unit of operating time — the backbone of RCM and risk analysis.
