Overall Equipment Effectiveness (OEE) is one of the most widely used performance indicators in manufacturing and industrial operations. It helps organizations understand how effectively equipment is being utilized compared to its maximum potential.
OEE measures the percentage of planned production time that is truly productive. It combines three key factors: Availability, Performance, and Quality.
Availability reflects how often equipment runs when scheduled. Downtime such as breakdowns or setup losses reduce availability.
Performance measures whether equipment runs at its designed speed. Slow cycles and minor stoppages reduce performance efficiency.
Quality indicates how many good parts are produced compared to total production. Scrap and rework reduce the quality score.
OEE = Availability × Performance × Quality
Each component is expressed as a percentage. The final OEE value represents true productive efficiency.
These tools help engineers and plant managers analyze manufacturing efficiency and production performance.
