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.
