Benchmark machine productivity and identify hidden capacity loss by measuring the three core factory metrics: Availability, Performance Rate, and Quality Yield.
The Three Pillars of OEE
OEE is the gold standard for measuring manufacturing productivity:
Availability Rate:Operating Time / Planned Production Time (Lost to breakdowns, setups, changeovers)
Performance Rate:(Ideal Cycle Time × Total Units) / Operating Time (Lost to slow cycles, minor stops)
Quality Yield:Good Units / Total Units Produced (Lost to scrap, rework, defects)
OEE = Availability Rate × Performance Rate × Quality Rate Availability = (Shift Time − Planned Breaks − Unplanned Downtime) / (Shift Time − Planned Breaks) Quality = (Total Produced − Defective Units) / Total Produced
Frequently Asked Questions
Typical Indian manufacturing plants operate between 50% to 65% OEE. An OEE score of 70% is considered good, while 85%+ is world-class Lean manufacturing standard.

In most factories, changeover setup times (die/mold changes) and minor machine idling/stoppages are the biggest hidden culprits of OEE loss.
