Understanding OEE

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

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
