1, Downtime Losses
(1) Equipment failures
(2) Set-up and adjustments
2, Speed Losses
(3) Idling and minor stoppages
(4) Reduced speed (actual operating vs. designed)
3, Defect Losses
(5) Defects in process
(6) Reduced yield between start of production and stable production.
1, Operator Time Losses
Manpower losses due to operation time being done more slowly than standard time (Cycle time > Standard Time)
2, Material Losses
Losses in yield due to "inherent waste" (Cut-off stock, Set-up pieces, prototype, etc.)
Energy losses such as electricity, gas, and water when machinery is not doing value-added work.
Idling losses due to inadequate sensors and product buildup on conveyors and chutes.
