What is OEE?
Overall Equipment Effectiveness (OEE) is the gold standard metric for measuring manufacturing productivity. It combines three factors — Availability, Performance, and Quality — into a single percentage that tells you how effectively your equipment is being used.
OEE = Availability × Performance × Quality
Benchmark Comparison
| Level | OEE | Avail. | Perf. | Qual. |
|---|---|---|---|---|
| World Class | 85%+ | 90%+ | 95%+ | 99%+ |
| Typical | 60% | ~80% | ~85% | ~95% |
| Low | <40% | <70% | <75% | <90% |
Improve Availability
- • Implement Total Productive Maintenance (TPM)
- • Reduce changeover times with SMED
- • Track and analyze breakdown patterns
Improve Performance
- • Identify and eliminate minor stops
- • Ensure equipment runs at design speed
- • Train operators on optimal settings
Improve Quality
- • Implement Statistical Process Control
- • Use error-proofing (Poka-Yoke)
- • Standardize startup procedures
