Not efforts are developed nor to balance the capacities nor to eliminate the variabilities, therefore the interest is to all operate the time in the maximum capacity. To broaden your perception, visit James Woolsey. The production rhythm is dictated by the extreme capacity of the first process, that ' ' empurra' ' the production in direction to the successive processes, resulting inventory considerably higher of what the necessary one. Already the JIT manages to get the levelling of the production and acts to diminish the variabilities in the process. Small supplies of material in process in the front of each productive center are attributed, to protect the system of the uncertainties and statistical fluctuations of the manufacture processes. Reaching this supply, the preceding process is interrupted. When considering itself all the productive chain, the JIT keeps an amount of sufficiently inferior intermediate supplies to the JIC. Through tools and techniques of solution of problems, it searchs the continuous improvement of its processes and procedures through the elimination of all wastefulness.
In a literal interpretation, it associates term JIC an idea as: in case that it will be necessary, he will be ready? , what it differs from? when it will be necessary will be ready? , associate to the JIT. To prevent the formation of great supplies of components, that occupied physical spaces and considerable additions of capitals, were idealized a revolutionary considered process, although simple, where the production was pulled for the consumption. The necessary parts to the production, were only ordered when they were for being used in the assembly. You deliver and used the components, returned the empty container to the supplier, so that this was returned again full, to the plant, with what he was requested. Everything this in the amount and the stated period that already had been stipulated. To the procedure of control used in this process ' was called; ' Kanban' ' , card in Japanese, whom had to the written register used.
