What does the Overall Equipment Effectiveness (OEE) metric measure?

The Overall Equipment Effectiveness (OEE) metric is a comprehensive measure that assesses the efficiency of equipment performance in manufacturing processes. It takes into account three key factors: availability, performance, and quality.

• Availability assesses whether the equipment is operational when it is scheduled to be running.

• Performance measures the speed at which the equipment operates compared to its designed speed.

• Quality evaluates the proportion of products that meet quality standards without defects.

By understanding OEE, organizations can identify areas for improvement in their operations, thereby maximizing productivity and efficiency. The metric is crucial for Total Productive Maintenance (TPM) as it helps teams focus on enhancing equipment reliability and effectiveness.

Other options do not directly pertain to the specific measurement and operational focus that OEE provides. For instance, the quality of raw materials, employee hours worked, and total production output are important metrics but do not reflect the combined effectiveness of equipment in a manufacturing context as OEE does.
