Philosophy based on the procedure of the Japanese company Toyota. The automobile company began to use its own production system that was perfected over time until it reached what we know today as Just in time. It consists of producing the right quantity of a product at the necessary time, combining flexibility, quality and cost. The JIT method spread among the main Japanese companies and, later, in Western companies.
Soon, this philosophy began to be applied in all areas of the company thanks to the improvements in competitiveness experienced by the organizations that applied it.
The revolutionary thing about this system is that it goes from a Push type methodology, where each phase of the chain production accumulates until it is required by the next phase, to a Pull type methodology, where each phase is the one that requests the required quantity from the previous phase of the supply chain, thus producing only what is necessary.
