Frequently asked questions
What is OEE (Overall Equipment Effectiveness)?
OEE is the gold-standard metric for how effectively a machine or line runs versus its full potential. It combines three factors into a single percentage, where 100% means producing only good parts, as fast as possible, with zero stop time.
What are the three factors of OEE?
Availability measures the share of scheduled time the equipment actually runs (lost to breakdowns and changeovers), Performance measures actual speed versus ideal cycle time (lost to minor stops and slow cycles), and Quality measures good units versus total units produced (lost to scrap and rework). OEE is the product of all three.
What is a good OEE score?
For discrete manufacturers, 85% is considered world-class, 60% is fairly typical, and 40% is common for plants just starting to measure. Even a few points of improvement usually means meaningful gains in throughput without new capital equipment.
How does BizOps track OEE live?
BizOps connects to machine signals and operator logs to capture downtime, cycle counts, and reject reasons in real time, then computes Availability, Performance, and Quality automatically. Teams see live OEE per line and shift on shop-floor dashboards, with alerts and Pareto loss analysis so you can act on the biggest losses first.
