Use **OEE by workstation** to analyze a workstation during a specific period. The view separates results into occupancy, availability, performance, and quality. ## Review OEE **Path:** **Smart Factory > Dashboards > OEE by workstation** ### 1. Choose the workstation and period Filter by workstation and the interval you want to analyze. ### 2. Interpret results Compare components to identify where losses are concentrated. #### Occupancy Measures the share of the selected period planned for production, after deducting planned downtime. **How is it calculated?** Occupancy (%) = (Planned production time / Total period time) \* 100 * **Planned production time:** the workstation's scheduled time minus planned downtime that stopped it. The summary shows it as **Productive**. * **Total period time:** the entire selected interval, including hours outside the shift. The summary shows it as **Total**. **What does low occupancy mean?** Lower occupancy means a smaller share of the period was planned for production. Review: * **Hours outside the shift:** the period may include nights, weekends, or other windows without scheduled activity. * **Planned downtime:** planned breaks or maintenance reduce the time planned for production. * **Shift configuration:** check that the workstation's schedule reflects the windows when it should work. To see how much of that time was actually used, check **Availability**. #### Availability Measures the share of planned production time with operations running within the shift. **How is it calculated?** Availability (%) = (Actual operating time / Planned production time) \* 100 * **Actual operating time:** time with operations running within the shift. The summary shows it as **Running**. * **Planned production time:** the workstation's scheduled time minus planned downtime that stopped it. The summary shows it as **Productive**. Unplanned stops and time without running operations reduce availability. Work outside the shift appears separately as **Running (unscheduled)**. **What does low availability mean?** A low value indicates that the workstation spends too much time stopped and is not producing when it should. Main causes commonly include: * Breakdowns, technical failures, or setup recorded as unplanned stops. * Waiting for materials, tools, or a previous operation. * Time without running operations due to insufficient workload or staff. * Incomplete records: if operators forget to pause or resume operations, downtime may be recorded as productive time or the reverse. #### Performance Measures actual manufacturing speed compared with the standard theoretical speed or time defined in the recipe or process. **How is it calculated?** Performance (%) = (Theoretical time / Actual production time) \* 100 * **Theoretical time:** obtained by multiplying produced quantity by the standard time defined in the recipe or process, adjusted for the workstation's assigned efficiency. * **Actual production time:** sum of recorded durations while the order was running. **What does low performance mean?** A low value indicates that the machine or operator works below expected capacity. Main causes commonly include: * Reduced speeds due to machine or equipment wear. * Recurring small stops that are not formally recorded. * Overly demanding theoretical time or standard speed. #### Quality Measures good pieces as a percentage of all pieces produced (good + rejected). **How is it calculated?** Quality (%) = (Good unit quantity / Total produced quantity) \* 100 * **Good unit quantity:** conforming pieces moving to the next operation or stock. * **Total produced quantity:** sum of good and rejected units recorded at the workstation. **What does low quality mean?** A low value indicates a high proportion of rejected units. Review these possible causes: * **Defective raw materials or semi-finished inputs:** pieces or materials arriving with faults from suppliers or previous operations. * **Setup errors at lot start:** incorrect calibrations generating rejects until the machine stabilizes. * **Tool or machine wear:** worn tooling causing deviations outside tolerance. * **Handling errors:** mistakes positioning, handling, or processing a piece. #### OEE (Overall Equipment Effectiveness) This is the workstation's overall productive efficiency indicator. **How is it calculated?** OEE (%) = (Availability / 100) \* (Performance / 100) \* (Quality / 100) \* 100 **What does low OEE mean?** A low OEE indicates that the workstation operates below its theoretical potential. Depending on the calculation's components, main causes commonly include: * **Availability losses:** frequent breakdowns, long setups, missing materials, or unplanned stops. * **Performance losses:** lower speed from wear, small stops, or unrealistic theoretical times. * **Quality losses:** waste, setup deviations at lot start, or raw material problems. Low OEE does not always indicate the same problem. First review which component falls, then open operational details. ## Related * [Dashboards](/en/concepts/manufacturing/dashboards) * [Analyze stops and production losses](/en/guides/manufacturing/analyze-stops-and-production-losses) * [Execute shop floor operations](/en/guides/manufacturing/execute-shop-floor-operations) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
