OEE & Reliability

OEE is useful when it exposes where productive time is being lost; it is misleading when the inputs or loss categories are poorly defined.

What this topic covers

What OEE should help you understand.

OEE combines availability, performance and quality, but the percentage is only the beginning. The value comes from the loss tree underneath it and the action it drives.

  • Define planned production time and downtime categories consistently.
  • Separate speed loss, micro-stoppages and quality loss instead of hiding them in one number.
  • Use OEE with maintenance and process evidence to prioritize reliability work.

A higher OEE number is not the goal by itself; more stable, useful production output is.
