Comparing OEE Scores - how high should you aim?

Over the years the idea of an 85% world-class OEE score has been incorrectly disseminated...

If you’re working in a machining centre then 85% is world class - but if you’re running something like a flour mill or indeed, most continuous processes, world class performance is above 90% OEE.

See the table below for world-class OEE targets by industry:

The true value of OEE is uncovering lost opportunity so that teams can work towards upward improvement trends. Continuous Improvement teams, depending on the effectiveness of the changes implemented, should expect to make the following OEE improvements over a 12 month period:

• Average - 5 or 6% improvement
• Good - 8 to 10% improvement
• Excellent - 15 to 25% improvement

Whilst comparing the OEE score between assets, departments, divisions, or even companies can be very misleading - measuring the improvement trend is a valuable pointer to show the health of a process.
