Formula
OEE = Availability × Performance × Quality, where Availability = run time ÷ planned time, Performance = (ideal cycle time × total units) ÷ run time, and Quality = good units ÷ total units.
What the result means
The headline result summarizes preventive maintenance oee for the values entered. Read it alongside the supporting measures, because a change in workload, staffing, delay, or quality can move the result for very different reasons.
This is an operational estimate. Keep definitions and time boundaries consistent when comparing teams, assets, or periods.
