Overall Equipment Effectiveness (OEE) is – at its most simple – a measurement of manufacturing productivity. Developed as a tenet of lean manufacturing, the aim of OEE is to provide metrics that can be used to improve a manufacturing process.
Three components provide data when assessing OEE, as described at www.oee.com. The first is availability, which measures whether the process is running as scheduled. The second factor, performance, assesses whether maximum manufacturing speeds are reached. Quality, which counts defects, is the third component.
