Attract the necessary product of the previous process in the amount of necessary time

Posted in Toyota Production System

Successful implementation of this rule depends on the underwriting of workers that the system is useful and easy to administer. This rule will probably be found with many obstacles because it requires a complete change from the previous production system.

Sub rule which became part of this rule are:
– Any withdrawal without going through the kanban should be banned
– Any withdrawal greater than the number of kanban should be banned
– A kanban must be attached to the physical product.

Refinement of production or increase daily production, is a necessary condition for a withdrawal and small-lot production of a continuous process, and most importantly, apply rules 1. Smoothing of production, for example: only if the kanban system is applied to pull parts from outside companies subcontract, then the kanban is a very dangerous weapon and uses the original will be lost. Subcontractors need of supplies, equipment, and manpower in large numbers to respond to fluctuating demand from manufacturers.

However, even if rule 1 is applied, JIT production cannot be easily achieved because the kanban system is merely the means of dispatching to the actual production activities every day in every process. Before entering the phase of dispatching jobs with kanban, the overall planning of the entire plant must be made in advance.
