Introduction

Just in time, is a manufacturing system developed originally by Toyota, based on eliminating the wastes by producing the required amount and filling the stock in the right time, subsequently the concept of lean manufacturing has formed and it focused on using the manufacturing system as a tools mixed together to reduce the inventory and other non added values elements. In this essay we intend to examine the reasons behind the development of JIT and the lean system, what made such processes surpass the other manufacturing systems and how were they implemented, precisely inside Toyota, the company which developed the JIT system. Furthermore we will investigate the new developed methods and processes that being performed with JIT and made it more flexible and efficient. Finally a brief futuristic look of what can we expect from this system, will JIT maintain its position among the other manufacturing processes under the unpredicted global economic changes? this article will curry a discussion on these inquiries and describe how did these system formed.

Discussion

To have a decent understanding on how JIT devolved and to predict its future, we must have a comprehensive view on the manufacturing process development time-line. Examining the past and how the philosophy of using machines to make a mass production for one item started, then how the relation between man/machine and machine evolved and why did JIT and the Lean systems had been developed?

Toyota Lean Principle Lean Manufacturing started as the Toyota Production System (TPS), developed by the Toyoda (now Toyota) Motor Car Company. Toyoda started by the manufacturing of looms for manufacturing cloth, then branched into bicycles before WWII.

In time, Toyoda (now Toyota) started to manufacture engines, small delivery vehicles, trucks, and cars. Poor management decisions almost put the company into bankruptcy. Losing face, the Sr. Management resigned, and/or changed their ways. They changed the name of the company (Toyoda to Toyota), granted workers life-long employment, and went on an aggressive improvement program to try and work their way back from near oblivion. The motivations for TPS were now established. Soon the tools and techniques started to emerge that eased the frustrations with the old, inefficient ways, and allowed Toyota to achieve its TPS goals.

Toyota's engineers looked to Henry Ford (inventor of the assembly line), Taylor (inventor of Modern Management techniques and Industrial Engineering), and Dr. W. Edwards Deming (Father of Modern Quality Management). Based on these early beginnings, the techniques were refined, honed, and improved in all areas.

With the invasion of the North American market by Volkswagon in the 1960's, and Toyota in the 1970's, and a world-wide recession, the American automotive industry was in for major changes and de-stabilization.

North American automotive watchdogs were looking for an explanation as to how Toyota could manufacture a ...
