Why it Matters ?

Tracks efficiency, performance, and quality.

In-depth Use Case / Real-world Example

OEE gives a snapshot of how well manufacturing equipment is performing. It’s calculated as: OEE = Availability × Performance × Quality. For example, a packaging machine might be available 90% of the time, operating at 95% speed, and producing 98% good units. So, OEE = 0.90 × 0.95 × 0.98 = 83.6%. A high OEE means machines are running smoothly, quickly, and with minimal defects. If OEE drops, it signals issues like frequent breakdowns, slow cycles, or high rework rates. In a real-world example, a food processing company might monitor OEE daily to identify underperforming machines and schedule timely maintenance. Tracking this metric helps maximize throughput and reduce waste and downtime.
