Definition
OEE shows how much of planned production time is actually used to produce good units at the intended speed. It is calculated as availability × performance × quality.
Key facts
- Availability accounts for downtime losses.
- Performance captures speed loss and short interruptions.
- Quality accounts for scrap and rework.
- Definitions must remain consistent across time and assets.
How is OEE (Overall Equipment Effectiveness) calculated?
Availability compares runtime with planned production time. Performance compares actual output with theoretical speed. Quality measures the share of good units.
What influences OEE (Overall Equipment Effectiveness)?
OEE helps distinguish technical losses from process, material, or quality issues. Maintenance should interpret the number together with production and quality teams.
How should teams interpret OEE (Overall Equipment Effectiveness)?
OEE is a loss-analysis tool rather than an isolated performance target. Improving one factor should never compromise safety, product quality, or asset life.
