Lean principles are derived from the Japanese manufacturing industry. California before joining MIT for MBA studies. As waste is eliminated quality improves while production time and cost are reduced. This is a fundamentally different approach from most improvement methodologies, and requires considerably more persistence than basic application of the tools, which may partially account for its lack of popularity. The difference between these two approaches is not the goal itself, but rather the prime approach to achieving it.
The implementation of smooth flow exposes quality problems that already existed, and thus waste reduction naturally happens as a consequence. The advantage claimed for this approach is that it naturally takes a system-wide perspective, whereas a waste focus sometimes wrongly assumes this perspective. Both lean and TPS can be seen as a loosely connected set of potentially competing principles whose goal is cost reduction by the elimination of waste. The disconnected nature of some of these principles perhaps springs from the fact that the TPS has grown pragmatically since 1948 as it responded to the problems it saw within its own production facilities. Thus what one sees today is the result of a ‘need’ driven learning to improve where each step has built on previous ideas and not something based upon a theoretical framework. Adherents of the Toyota approach would say that the smooth flowing delivery of value achieves all the other improvements as side-effects.
The other of the two TPS pillars is the very human aspect of autonomation, whereby automation is achieved with a human touch. Lean implementation emphasizes the importance of optimizing work flow through strategic operational procedures while minimizing waste and being adaptable. However, adaptability is often constrained, and therefore may not require significant investment. More importantly, all of these concepts have to be acknowledged by employees who develop the products and initiate processes that deliver value.
The cultural and managerial aspects of lean are arguably more important than the actual tools or methodologies of production itself. There are many examples of lean tool implementation without sustained benefit, and these are often blamed on weak understanding of lean throughout the whole organization. Lean aims to enhance productivity by simplifying the operational structure enough to understand, perform and manage the work environment. All work shall be highly specified as to content, sequence, timing, and outcome.
Every customer-supplier connection must be direct, and there must be an unambiguous yes or no way to send requests and receive responses. The pathway for every product and service must be simple and direct. He added that avoiding unnecessary costs could be more profitable than increasing sales: “A penny saved is two pence clear. Remember what Poor Richard says, ‘Buy what thou hast no need of, and ere long thou shalt sell thy necessaries. In another place he says, ‘Many have been ruined by buying good penny worths’.
The introduction of a non-stooping scaffold, which delivered the bricks at waist level, allowed masons to work about three times as quickly, and with the least amount of effort. Taylor said: “And whenever a workman proposes an improvement, it should be the policy of the management to make a careful analysis of the new method, and if necessary conduct a series of experiments to determine accurately the relative merit of the new suggestion and of the old standard. And whenever the new method is found to be markedly superior to the old, it should be adopted as the standard for the whole establishment. American industrialists recognized the threat of cheap offshore labor to American workers during the 1910s, and explicitly stated the goal of what is now called lean manufacturing as a countermeasure. We are justly proud of the high wage rates which prevail throughout our country, and jealous of any interference with them by the products of the cheaper labor of other countries.
To maintain this condition, to strengthen our control of home markets, and, above all, to broaden our opportunities in foreign markets where we must compete with the products of other industrial nations, we should welcome and encourage every influence tending to increase the efficiency of our productive processes. Henry Ford initially ignored the impact of waste accumulation while developing his mass assembly manufacturing system. Ford’s success has startled the country, almost the world, financially, industrially, mechanically. It exhibits in higher degree than most persons would have thought possible the seemingly contradictory requirements of true efficiency, which are: constant increase of quality, great increase of pay to the workers, repeated reduction in cost to the consumer. And with these appears, as at once cause and effect, an absolutely incredible enlargement of output reaching something like one hundredfold in less than ten years, and an enormous profit to the manufacturer. Not only is everything done by hand, but seldom is a thought given to a logical arrangement. A farmer doing his chores will walk up and down a rickety ladder a dozen times.
He will carry water for years instead of putting in a few lengths of pipe. His whole idea, when there is extra work to do, is to hire extra men. He thinks of putting money into improvements as an expense. It is waste motion— waste effort— that makes farm prices high and profits low. Poor arrangement of the workplace—a major focus of the modern kaizen—and doing a job inefficiently out of habit—are major forms of waste even in modern workplaces. Ford also pointed out how easy it was to overlook material waste.
Ford and I were together he spotted some rust in the slag that ballasted the right of way of the D. This slag had been dumped there from our own furnaces. Ford said to me, ‘there’s iron in that slag. You make the crane crews who put it out there sort it over, and take it back to the plant. In other words, Ford saw the rust and realized that the steel plant was not recovering all of the iron.
Ford’s early success, however, was not sustainable. Womack and Daniel Jones pointed out in “Lean Thinking”, what Ford accomplished represented the “special case” rather than a robust lean solution. The major challenge that Ford faced was that his methods were built for a steady-state environment, rather than for the dynamic conditions firms increasingly face today. This was made clear by Ford’s precipitous decline when the company was forced to finally introduce a follow-on to the Model T. While Ford is renowned for his production line, it is often not recognized how much effort he put into removing the fitters’ work to make the production line possible. Previous to the use, Ford’s car’s components were fitted and reshaped by a skilled engineer at the point of use, so that they would connect properly.
