Workers send their output on to the next downstream work area as they finish
The voice of the engineer determines the production for the day
Work normally flows through the Quality Circle
Large batches are produced and stored to minimize setup time
If the output of a work group is not taken, the workers will simply stop production until the inventory is removed
The production schedule is prepared in advance for all workstations
In a pull system:
