In the classic KANBAN production control method, the demand source, the supply source and the procedure to be used to replenish the material are defined in the control cycle as well as the number of kanbans that circulate between the supply source and the demand source and the quantity per kanban.

In this classic KANBAN procedure, the kanban signal always only triggers replenishment for the kanban quantity defined in the control cycle. Moreover, you cannot circulate more kanbans than are defined in the control cycle without changing the control cycle first.
