Tool 03 / OEE

What's your true equipment effectiveness?

OEE is availability × performance × quality. Enter one shift's numbers to see where the losses actually hide — and the gap to world-class (85%).

Reading

Whether the drag is availability, speed, or scrap changes what you should buy or fix. Get a read on the highest-return move.

Availability: Run time ÷ planned time, where run time is planned time minus unplanned downtime.
Performance: (Ideal cycle time × total units) ÷ run time. Capped at 100% — if it exceeds that, your ideal cycle time is set too slow.
Quality: Good units ÷ total units produced. First-pass good only; reworked pieces don't count as good.
World-class: 85% OEE is the common benchmark (roughly 90% availability × 95% performance × 99.9% quality).
