Typical OEE by Manufacturing Type
Manufacturing TypeTypical OEEKey Challenges
Discrete Manufacturing60–75%Changeovers, minor stops, varied cycle times
Process Manufacturing80–90%Startup/shutdown losses, grade changes
Job Shop40–60%High changeover frequency, varied routings
Packaging Lines55–70%Micro-stops, product changeovers, material jams
Automotive Assembly75–85%Takt time adherence, quality requirements

World class is 85% OEE regardless of manufacturing type, as defined by the standard Availability 90% x Performance 95% x Quality 99.9% benchmark. The ranges above are typical observed performance, not separate world-class targets - process plants sit higher because they run continuously with few changeovers, job shops sit lower because they change over constantly.

How OEE Works

OEE = Availability × Performance × Quality
