Overall Equipment Effectiveness

Overall Equipment Effectiveness (OEE) is a commonly used measuring instrument and tool to measure the performance of the machines and production process, and to directly see their effectiveness. OEE is measured by combining Availability (A), Performance (P) and Quality (Q). It helps to identify potential losses and to understand where in the process it needs improvement. If you have invested in expensive machines, it is important that they are used effectively.

With OEE you calculate the ratio between theoretical maximum output and real output. When there is a difference, it helps you to detect where that difference is caused. OEE checks three things:
