Overall Labor Effectiveness (OLE) Calculator

How this is calculated

Overall Labor Effectiveness applies the OEE structure to people instead of a machine. The three factors are multiplied, not averaged, so each one is a gate on the others.

In the results bar, each segment is scaled to its factor, so the shrinking width shows how each stage takes a bite out of the paid labor hour before it becomes good output.

Reading OLE honestly

• The multiplicative penalty is the point. Three healthy-looking factors of 90%, 85%, and 97% still land near 74%, because losses compound rather than add. Averaging them would flatter the result.
• Definitions must be consistent. Availability, performance, and quality can each be measured several ways. Pick clear definitions and hold them steady, or period-to-period comparisons break.
• Labor, not machine. Availability here reflects people being present and working, performance reflects pace against a fair standard, and quality reflects first-pass good output attributable to labor.
• It is a direction, not a verdict. OLE points to where the biggest loss sits. It does not by itself explain why, and it should never be used to blame individuals.

OLE shares its math with OEE. To run the same three-factor calculation for a machine or line, use the OEE calculator and read the OEE calculation guide for how availability, performance, and quality are each defined.
