How it works
OEE = Availability × Performance × Quality, with each percentage expressed as a decimal. OEE is a composite manufacturing indicator, not a standalone explanation of losses.
Worked example
A factory line has 90% availability, 85% performance, and 98% quality. Its OEE is 74.97%.
Important limitations
Results depend on your input assumptions. Check your units and validate important business decisions against actual operating data.
