All Quotes by W. Edwards Deming
“It is not necessary to change. Survival is not mandatory.”
“Uncontrolled variation is the enemy of quality.”
“The worker is not the problem. The problem is at the top! Management!”
“Learning is not compulsory; it's voluntary. Improvement is not compulsory; it's voluntary. But to survive, we must learn.”
“Blame the process, not the people.”
“I think that people here expect miracles. American management thinks that they can just copy from Japan—but they don't know what to copy!”
“In Europe and in America, people are now more interested in the cost of quality and in systems of quality-audit. But in Japan, we are keeping very strong interest to improve quality by use of methods which you started....when we improve quality we also improve productivity, just as you told us in 1950 would happen.”
“Defects are not free. Somebody makes them, and gets paid for making them.”
“Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease costs.”
“Whenever there is fear, you will get wrong figures.”
“Quality comes not from inspection, but from improvement of the production process.”
“Part of America's industrial problems is the aim of its corporate managers. Most American executives think they are in the business to make money, rather than products or service...The Japanese corporate credo, on the other hand, is that a company should become the world's most efficient provider of whatever product and service it offers. Once it becomes the world leader and continues to offer good products, profits follow.”
“Learning is not compulsory... neither is survival.”
“Profit in business comes from repeat customers, customers that boast about your project or service, and that bring friends with them.”
“The supposition is prevalent the world over that there would be no problems in production or service if only our production workers would do their jobs in the way that they were taught. Pleasant dreams. The workers are handicapped by the system, and the system belongs to the management.”
“We cannot rely on mass inspection to improve quality, though there are times when 100 percent inspection is necessary. As Harold S. Dodge said many years ago, 'You cannot inspect quality into a product.' The quality is there or it isn't by the time it's inspected.”
“Foremost is the principle that the purpose of consumer research is to understand the customer's needs and wishes, and thus design product and service that will provide better living for him in the future. A second principle is that no one can guess the future loss of business from a dissatisfied customer...”
“Loss of market begets unemployment. Emphasis has been on short-term profit, to the undernourishment of plans that might generate new product and service that would keep the company alive and provide jobs and more jobs. It is no longer socially acceptable performance to lose market and to dump hourly workers on to the heap of unemployed.”
“The 14 points [for quality control] apply anywhere, to small organizations as well as to large ones...:”
“The prevailing - and foolish - attitude is that a good manager can be a good manager anywhere, with no special knowledge of the production process he's managing. A man with a financial background may know nothing about manufacturing shoes or cars, but he's put in charge anyway.”
“Statistical methods had taken fire in America around 1942, following a series of ten-day intensive courses for engineers, initiated by Stanford University on a suggestion from this author. The war department also gave courses at factories of suppliers. Brilliant applications attracted much attention, but the flare of statistical methods by themselves, in an atmosphere in which management did not know their responsibilities, burned, sputtered, fizzled and died out.”
“Why waste knowledge?... No company can afford to waste knowledge. Failure of management to breakdown barriers between activities... is one way to waste knowledge. People that are not working together are not contributing their best to the company. People as they work together, feeling secure in the job reinforce their knowledge and efforts. Their combined output, when they are working together, is more than the sum of their separate”
“The various segments of the system of profound knowledge proposed here cannot be separated. They interact with each other. Thus, knowledge of psychology is incomplete without knowledge of variation.”
“A manager of people needs to understand that all people are different. This is not ranking people. He needs to understand that the performance of anyone is governed largely by the system that he works in, the responsibility of management.”
“What is a system? A system is a network of interdependent components that work together to try to accomplish the aim of the system. A system must have an aim. Without an aim, there is no system. The aim of the system must be clear to everyone in the system. The aim must include plans for the future. The aim is a value judgment. (We are of course talking here about a man-made system.)”
“It is important that an aim never be defined in terms of a specific activity or method. It must always relate to a better life for everyone.”
“Choice of aim is clearly a matter of clarification of values, especially on the choice between possible options.”
“A system must be managed. It will not manage itself. Left to themselves in the Western world, components become selfish, competitive, independent profit centres, and thus destroy the system. . . . The secret is cooperation between components toward the aim of the organization. We can not afford the destructive effect of competition.”
“To successfully respond to the myriad of changes that shake the world, transformation into a new style of management is required. The route to take is what I call profound knowledge - knowledge for leadership of transformation.”
“Management’s job. It is management’s job to direct the efforts of all components toward the aim of the system. The first step is clarification: everyone in the organization must understand the aim of the system, and how to direct his efforts toward it. Everyone must understand the damage and loss to the whole organization from a team that seeks to become a selfish, independent, profit centre.”
“. . .the principle that where there is fear, there will be wrong figures. . . .”
“What is the variation trying to tell us about a process, about the people in the process?”
“Knowledge is theory. We should be thankful if action of management is based on theory. Knowledge has temporal spread. Information is not knowledge. The world is drowning in information but is slow in acquisition of knowledge. There is no substitute for knowledge.”
“I am forever learning and changing.”
“Experience by itself teaches nothing...Without theory, experience has no meaning. Without theory, one has no questions to ask. Hence without theory there is no learning.”
“You should not ask questions without knowledge.”
“It is not enough to do your best; you must know what to do, and then do your best.”
“Lack of knowledge... that is the problem.”
“A bad system will beat a good person every time.”
“We are here to make another world.”
