The number of kanban must be minimized

Because the number of kanban inventory reflects the maximum of the part, then it should be kept to a minimum. The total amount of each kanban cultivated fixed. Therefore, when the average daily demand has increased, lead time should be reduced. This requires a reduction in cycle time from standard operating routine to change the allocation of labor adjustment.

Kanban should be used to adapt to fluctuations in demand

Fitting well with the kanban production refers to the most interesting properties of the kanban system: The ability to adapt to sudden changes in demand or production of an emergency. Companies that do not use kanban system will lack a vehicle to act on it, changes in demand are not expected. Centralized control system used to determine production schedules and issue simultaneous production process; therefore, that sudden changes in demand will require at least seven to ten day intervals before the schedule can be updated and issued to the plant, the time interval for the computer to compile and calculate the most recent data. As a result, various production will face disconnection from time to time, mashing the changing needs of production; this issue will form a production process is less smooth.

Defective products should never be collected to the next process

Kanban system that would self-destruct unless all three rules are followed. If some part is damaged encountered, then the next process in itself makes the line stopped because there is no extra units of inventory and send the defective part to the previous process. Lines like this dismissal of the next process is very clear and visible to everyone. Also, faulty operation must be eliminated to ensure the withdrawal of rhythmic than the previous process. Standardization of work, therefore, one of the kanban system is an absolute requirement.
