OEE - Lean Manufacturing Metric

by Carl Wright - industrial engineer, ASQ Six Sigma Black Belt, and Master Black Belt.

Overall Equipment Effectiveness is the common machinery and process metric utilized through a lean manufacturing initiative.

The OEE concept normally measures the effectiveness of a machine center or process line, but can be utilized in non-manufacturing operations also.

The high level formula for the Lean Manufacturing OEE is:

OEE = Availability X Productivity X Quality.
Abbreviated, it is: OEE = A X P X Q.
