Overall Equipment Effectiveness
Overall Equipment Effectiveness (OEE) is a key performance indicator that measures how well a manufacturing asset is utilized compared to its full potential. It combines availability, performance, and quality.
TECHNICAL DEFINITION
Overall Equipment Effectiveness (OEE) is a foundational metric in Lean and TPM, calculated as the product of Availability (actual operating time vs. planned), Performance (actual speed vs. ideal speed), and Quality (good units vs. total units), offering a comprehensive view of manufacturing productivity losses.
BACKGROUND
Overall equipment effectiveness (OEE) is a measure of how well a manufacturing equipment is utilized compared to its full potential, during the periods when it is scheduled to run. It identifies the percentage of manufacturing time that is truly productive as well as the time it is losing effectiveness. An OEE of 100% means that only good parts are produced, at the maximum speed, and without interruption.
