The Overall Equipment Effectiveness (OEE) is a key figure, which describes the effectiveness of the complete production process. It is calculated by multiplying three factors:
- Availability (losses such as unplanned system downtimes)
- Output rate (deviations from the planned target performance), and
- Quality rate (scrap)
Using the OEE key figure you can assess your own effectiveness relative to a defined ideal state at a glance.
Typically, downtimes and their causes are documented, optimization potentials are exposed, and quality losses are documented.
