Overall Equipment Effectiveness (OEE)

Calculate OEE from planned time, downtime, runtime, ideal cycle time, total count, and good count.

💡 Engineering Knowledge PrimerOEE decomposes productive output into Availability, Performance, and Quality. It is a measurement KPI; it does not replace a loss tree, root-cause analysis, maintenance plan, or process-capability study.
OPERATING LIMITS — KPI calculation only; align product definitions, ideal-cycle standards, planned-stop rules, and loss classification before benchmarking.

Technical Methodology & Engineering Principles

GOVERNING EQUATION
Planned Production Time = Scheduled Time − Planned Downtime Availability = Run Time / Planned Production Time Performance = Ideal Cycle Time × Total Count / Run Time Quality = Good Count / Total Count OEE = Availability × Performance × Quality
Assumptions & Scope

All time and count inputs refer to the same reporting period; ideal cycle time is the validated best demonstrated rate for the product and equipment.

Operating Range & Boundary

Planned downtime cannot exceed scheduled time; run time cannot exceed planned production time; good count cannot exceed total count.
