Calculations
| Formula | Example |
| Lost Time Reworking Products = Number of Units Reworked / Target Speed per Unit/Min |
Given: Number of Units Reworked: 140 Units Target Speed per Unit/Min: 15 Units/min Computation: = 140 Units / 15 Units/min = 9.33 min of Lost Time |
| Number of Units Reworked = Weight of Rework / Target Weight Per Unit |
Given: Weight of Rework: 70 Kg Target Weight Per Unit: 0.5 Kg/Uni Computation: = 70 Kg / 0.5 Kg/Unit = 140 Units |
