The six big losses

Avaliability

Breakdown: equipment failure, tooling failure, unplanned maintenance
Setup and Adjustment: changeover, material shortage, warm-up time

Performance

Reduced Speed: rough running, equipment wear, operator inefficiency, incorrect settings
Small Stops: obstructed flow, jam, missfeed, sensor blocked, cleaning, checking

Quality

Startup Rejects: scrap, rework, in process damage, incorrect assembly
Production Reject: same as startup but during production
