Overall Equipment Effectiveness

Overall Equipment Effectiveness (OEE) is the single-number measure of how well a manufacturing operation runs its equipment, calculated as Availability × Performance × Quality and expressed as a percentage.

In depth

OEE captures losses from three distinct causes: time the machine is down when it should run (availability), time it runs slower than its rated speed (performance), and output that fails quality (quality). World-class OEE is typically cited around 85%; the point of the metric is not the number itself but the breakdown — it shows where to focus improvement effort. Azumuta contributes to OEE by reducing changeover times through standardized digital work instructions, catching quality losses at the step level, and feeding downtime reasons into live dashboards.
