A RUNNING LINE IS NOT YET A PRODUCTIVE LINE

OEE = A × P × Q = good casesplanned time × ideal rate

The top bar begins with ideal cases from an shift at cases per minute. Each gate removes one of the six big losses, and every figure comes from the same shift model. Availability removes breakdown and setup time, performance removes minor stops and reduced speed, and quality removes process and startup rejects. For a food manufacturer, the gap consumes scheduled line time, labor and ingredients without creating a saleable case. The line ships the product of all three factors, not the promise of any one.
