What is OEE?

OEE is a combination of three factors expressed as a percentage:

  • Equipment Availability
    • The amount of available time actually used for production
  • Performance Efficiency
    • The rate at which the equipment ran compared with its design speed
  • Quality Rate
    • The proportion of good product made


OEE % = Availability % * Efficiency %* Quality %

This is an overall measure of the effectiveness of the machinery.

The Modus7 calculation of these factors conforms to the Internationally recognized manufacturing standards.
