Since Henry Ford invented the mounting and Assembly chain, industrial innovators focused on constant improvement through a variety in the implementation of different manufacturing strategies. Lean Manufacturing is a strategy of manufacturing that seeks to produce and generate a high level of performance with a minimum of inventory. A Japanese methodology known as the Toyota production system, very similar to Lean Manufacturing, designed by Sakichi Toyoda, originally focused on manufacturing centers around the placement of small stocks of inventory at strategic locations around the Assembly line, rather than implement centralized warehouses. These small reserves are known as Kanban and the use of the same significantly reduces waste and increases productivity in the factory also optimized the different market and distribution networks. In addition to the Elimination of waste, efficiency in manufacturing aims to provide optimum quality through construction of a method by which each part is inspected immediately after manufacture, and if there is a defect, the production line is stopped so that the problem can be detected in the shortest possible time. Lean manufacturing method, as it is also known to Lean Manufacturing, has much in common with the strategy of management of Total quality (a kind of quality Control). Both strategies empower workers on the Assembly line and in the belief that the production operators have greater knowledge of how the system of production in the should work.
In a Lean Manufacturing system, providers deliver small lots on a daily basis, and the machines should not necessarily operate at full capacity. One of the main focuses of lean manufacturing is to eliminate waste, i.e. anything that does not add value to the final product will be eliminated. In this sense, large inventories are seen as a type of waste which carries with it a high cost. One of the main foundations of this strategy is to train workers and make production decisions at the lowest possible level. In addition, factors offer a large measure of chain of Lean Manufacturing management and close collaboration with suppliers in this aspect is needed, what facilitates the rapid flow of product and parts to the plant. Lean Manufacturing strategies can save millions of dollars to large companies or SMEs and produce excellent results. Advantages include lower production times, reducing times of preparation, lower spending of teams, and of course, the increase in profits. With this concept is given to the manufacturers a competitive advantage by reducing costs and increasing quality, also allows the manufacturer more responsive to the demands of customers.
