Example of an OEE Combined chart that displays the overall OEE metric and its submetrics:

(overall OEE) Example

Availability = 75.1%

Performance = 87.8%

Quality = 89.8%

OEE = Availability (75.1%) x Performance (87.8%) x Quality (89.8%)

OEE = 59.2%

To see how each of these metrics was calculated for this example, see:

Good OEE percentages

It can be misleading to compare OEE numbers between manufacturers, or from plant to plant within the same company because no two plants, products, equipment, or human assets are identical. A good use for OEE numbers then is to establish baseline percentages for your organization and work to improve them—without comprising first-pass yield.

Following are OEE percentages that are typically considered to be good.

Availability      90%

Performance   95%

Quality            99.9% (may be low for some Six Sigma initiatives)

Overall OEE     85%+ for World Class Manufacturing (60% is average).
