Just in time (JIT) - 5 Zeros
Just in time is a method of managing production inspired by Toyota production system. The method is based on an organization of production according to the principle of five zeros
ZERO DEFECT - The product produced must have an irreproachable quality. The cost of returning to the factory is excessively expensive depending on the type of product (for example, returning vehicles from a large company to the factory due to a mechanical or technical defect). The cost of customer dissatisfaction is also to be taken into account, since an unsatisfied customer is a lost customer. In addition, quality controls must be rigorous and carried out at each stage of the manufacturing process.
ZERO PAPER - Ecology is a growing concern worldwide. Today, this point is essential. Indeed, respecting the zero paper rule not only generates savings on the purchase of consumables, but also, this practice is ecological, because it saves thousands of trees by eliminating the consumption of tons of paper. This rule is increasingly applied in the production and / or order preparation processes by the use of RFID or RF guns or voice preparation.
ZERO INVENTORY - Just-in-time strategy includes making the right products available at the right time. The goal is to avoid unnecessary storage. The inventory immobilizes money and space without generating added value to the products stored. In addition, the inventory must be monitored, which constitutes a factor of additional expenditure (material and human).
ZERO DELAY - Once the order has been issued by the customer, the preparation, packaging and shipping processes must be carried out as quickly as possible and without downtime so that the customer receives the order in a minimum delay. Each step must be optimized so that there is never a break in the process.
ZERO BREAKDOWN - The best way to ensure reliable and continuous production and to avoid time-consuming and costly downtime is to keep the production equipment running smoothly. This involves maintenance, preventive maintenance, the use of the tool within the framework provided for this purpose, etc.
Just-in-time well used generates real productivity gains. It allows, in fact, to optimize the use of the working time of the operators while involving them in a concrete way in their activities. Finally, it lays the foundations for the continuous improvement cycles necessary for the renewal and optimization of manufacturing processes
