William Edwards Deming (October 14, 1900–December 20, 1993) was an American statistician, college professor, author, lecturer, and consultant. Deming is widely credited with improving production in the United States during World War II, although he is perhaps best known for his work in Japan. There, from 1950 onward he taught top management how to improve design (and thus service), product quality, testing and sales (the last through global markets)[1] through various methods, including the application of statistical methods such as analysis of variance (ANOVA) and hypothesis testing. Deming made a significant contribution to Japan's later renown for innovative high-quality products and its economic power. He is regarded as having had more impact upon Japanese manufacturing and business than any other individual not of Japanese heritage. Despite being considered something of a hero in Japan, he was only beginning to win widespread recognition in the U.S. at the time of his death. [2]

## Overview Edit

Ford Motor Company was simultaneously manufacturing a car model with transmissions made in Japan and the United States. Soon after the car model was on the market, Ford customers were requesting the model with Japanese transmission over the USA-made transmission, and they were willing to wait for the Japanese model. As both transmissions were made to the same specifications, Ford engineers could not understand the customer preference for the model with Japanese transmission. It delivered smoother performance with a lower defect rate. Finally, Ford engineers decided to take apart the two different transmissions. The American-made car parts were all within specified tolerance levels. On the other hand, the Japanese car parts had much closer tolerances than the USA-made parts - i.e. if a part was supposed to be one foot long, plus or minus 1/8 of an inch - then the Japanese parts were within 1/16 of an inch. This made the Japanese cars run more smoothly and customers experienced fewer problems. This is an example of Dr. Deming's teachings, having been adopted by the Japanese, delivering better quality products [3].

Deming was born in Sioux City, Iowa. He received a B.S. in electrical engineering from the University of Wyoming at Laramie (1921), an M.S. from the University of Colorado (1925), and a Ph.D. from Yale University (1928). Both graduate degrees were in mathematics and physics. Deming had an internship at Bell Telephone Laboratories while studying at Yale. He subsequently worked at the U.S. Department of Agriculture and the Census Department. While working under Gen. Douglas MacArthur as a census consultant to the Japanese government, he famously taught statistical process control methods to Japanese business leaders, returning to Japan for many years to consult and to witness economic growth that he had predicted as a result of application of techniques learned from Walter Shewhart at Bell Laboratories. Later, he became a professor at New York University while engaged as an independent consultant in Washington, D.C.

Deming was the author of Out of the Crisis (1982–1986) and The New Economics for Industry, Government, Education (1993), which includes his System of Profound Knowledge™ and the 14 Points for Management (described below). Deming played flute & drums and composed music throughout his life, including sacred choral compositions and an arrangement of The Star Spangled Banner.[4]

In 1993, Deming founded the W. Edwards Deming Institute in Washington, D.C., where the Deming Collection at the U.S. Library of Congress includes an extensive audiotape and videotape archive. The aim of the W. Edwards Deming Institute is to foster understanding of The Deming System of Profound Knowledge™ to advance commerce, prosperity and peace.[5]

## Early life and work Edit

Born in Sioux City, Iowa, Deming was raised in Polk City, Iowa on his grandfather's chicken farm, then later in Powell, Wyoming. His father's name was also William, so he was called Edwards (the maiden name of his mother, Pluma Irene Edwards).[6] In 1917, he enrolled in the University of Wyoming at Laramie, graduating in 1921 with a B.S. in electrical engineering. In 1925, he received an M.S. from the University of Colorado, and in 1928, a Ph.D. from Yale University. Both graduate degrees were in mathematics and mathematical physics. Deming worked as a mathematical physicist at the United States Department of Agriculture (1927–39), and was a statistical adviser for the United States Census Bureau (1939–45). He was a professor of statistics at New York University's graduate school of business administration (1946–1993), and he taught at Columbia University's graduate School of business (1988–1993). He also was a consultant for private business.

In 1927, Deming was introduced to Walter A. Shewhart of the Bell Telephone Laboratories by Dr. C.H. Kunsman of the United States Department of Agriculture (USDA). Deming found great inspiration in the work of Shewhart, the originator of the concepts of statistical control of processes and the related technical tool of the control chart, as Deming began to move toward the application of statistical methods to industrial production and management. Shewhart's idea of common and special causes of variation led directly to Deming's theory of management. Deming saw that these ideas could be applied not only to manufacturing processes but also to the processes by which enterprises are led and managed. This key insight made possible his enormous influence on the economics of the industrialized world after 1950.[7]

Deming edited a series of lectures delivered by Shewhart at USDA, Statistical Method from the Viewpoint of Quality Control, into a book published in 1939. One reason he learned so much from Shewhart, Deming remarked in a videotaped interview, was that, while brilliant, Shewhart had an "uncanny ability to make things difficult." Deming thus spent a great deal of time both copying Shewhart's ideas and devising ways to present them with his own twist.[8]

Deming developed the sampling techniques that were used for the first time during the 1940 U.S. Census. During World War II, Deming was a member of the five-man Emergency Technical Committee. He worked with H.F. Dodge, A.G. Ashcroft, Leslie E. Simon, R.E. Wareham, and John Gaillard in the compilation of the American War Standards (American Standards Association ZI.1-3 published in 1942)[9] and taught statistical process control (SPC) techniques to workers engaged in wartime production. Statistical methods were widely applied during World War II, but faded into disuse a few years later in the face of huge overseas demand for American mass-produced products.

### Work in Japan Edit

In 1947, Deming was involved in early planning for the 1951 Japanese Census. The Allied powers were occupying Japan, and he was asked by the U.S. United States Department of the Army to assist with the census. While Deming was there, his expertise in quality control techniques, combined with his involvement in Japanese society, led to his receiving an invitation from the Japanese Union of Scientists and Engineers (JUSE).[6]

JUSE members had studied Shewhart's techniques, and as part of Japan's reconstruction efforts, they sought an expert to teach statistical control. During June–August 1950, Deming trained hundreds of engineers, managers, and scholars in statistical process control (SPC) and concepts of quality. He also conducted at least one session for top management.[10] Deming's message to Japan's chief executives: improving quality will reduce expenses while increasing productivity and market share.[1] Perhaps the best known of these management lectures was delivered at the Mt. Hakone Conference Center in August of 1950.

A number of Japanese manufacturers applied his techniques widely and experienced theretofore unheard of levels of quality and productivity. The improved quality combined with the lowered cost created new international demand for Japanese products.

Deming declined to receive royalties from the transcripts of his 1950 lectures, so JUSE's board of directors established the Deming Prize (December 1950) to repay him for his friendship and kindness.[10] The Deming Prize—especially the Deming Application Prize, which is given to companies—has exerted an immeasurable influence directly or indirectly on the development of quality control and quality management in Japan.[11][12]

### HonorsEdit

In 1960, the Prime Minister of Japan (Nobusuke Kishi), acting on behalf of Emperor Hirohito, awarded Dr. Deming Japan’s Order of the Sacred Treasure, Second Class.[13] The citation on the medal recognizes Deming's contributions to Japan’s industrial rebirth and its worldwide success. The first section of the meritorious service record describes his work in Japan:[10]

• 1947, Rice Statistics Mission member
• 1950, assistant to the Supreme Commander of the Allied Powers
• instructor in sample survey methods in government statistics

The second half of the record lists his service to private enterprise through the introduction of epochal ideas, such as quality control and market survey techniques.

### Later work in the U.S. Edit

David Salsburg wrote:

"He was known for his kindness to and consideration for those he worked with, for his robust, if very subtle, humor, and for his interest in music. He sang in a choir, played drums and flute, and published several original pieces of sacred music." (page 254, The Lady Tasting Tea)[14]

Later, from his home in Washington, D.C., Dr. Deming continued running his own consultancy business in the United States, largely unknown and unrecognized in his country of origin and work. In 1980, he was featured prominently in an NBC documentary titled If Japan can... Why can't we? about the increasing industrial competition the United States was facing from Japan. As a result of the broadcast, demand for his services increased dramatically, and Deming continued consulting for industry throughout the world until his death at the age of 93.

Ford Motor Company was one of the first American corporations to seek help from Deming. In 1981, Ford recruited Deming to help jump-start its quality movement. Ford's sales were falling. Between 1979 and 1982, Ford had incurred $3 billion in losses. Deming questioned the company's culture and the way its managers operated. To Ford's surprise, Deming talked not about quality but about management. He told Ford that management actions were responsible for 85% of all problems in developing better cars. After 1982, Ford came out with a profitable line of cars, the Taurus-Sable line. In a letter to Autoweek Magazine, Donald Petersen, then Ford Chairman, said, "We are moving toward building a quality culture at Ford and the many changes that have been taking place here have their roots directly in Dr. Deming's teachings."[15] By 1986, Ford had become the most profitable American auto company. For the first time since the 1920s, its earnings had exceeded those of arch rival General Motors (GM). Ford had come to lead the American automobile industry in improvements. Ford's following years' earnings confirmed that its success was not a fluke, for its earnings continued to exceed GM and Chrysler's. In 1982, Dr. Deming, as author, had his book published by the MIT Center for Advanced Engineering as Quality, Productivity, and Competitive Position, which was renamed Out of the Crisis in 1986. Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved products and services. "Long-term commitment to new learning and new philosophy is required of any management that seeks transformation. The timid and the fainthearted, and the people that expect quick results, are doomed to disappointment." Over the course of his career, Deming received dozens of academic awards, including another, honorary, Ph.D. from [Oregon State University. In 1987 he was awarded the National Medal of Technology: "For his forceful promotion of statistical methodology, for his contributions to sampling theory, and for his advocacy to corporations and nations of a general management philosophy that has resulted in improved product quality." In 1988, he received the Distinguished Career in Science award from the National Academy of Sciences.[6] In 1993, Dr. Deming published his final book, The New Economics for Industry, Government, Education, which included the System of Profound Knowledge™ and the 14 Points for Management. It also contained educational concepts involving group-based teaching without grades, as well as management without individual merit or performance reviews. In December 1993, W. Edwards Deming died in his sleep at his Washington home at about 3 a.m. due to "natural causes." His family was by his side when he died.[16] ## Deming philosophy synopsis Edit The philosophy of W. Edwards Deming has been summarized as follows: "Dr. W. Edwards Deming taught that by adopting appropriate principles of management, organizations can increase quality and simultaneously reduce costs (by reducing waste, rework, staff attrition and litigation while increasing customer loyalty). The key is to practice continual improvement and think of manufacturing as a system, not as bits and pieces."[17] In the 1970s, Dr. Deming's philosophy was summarized by some of his Japanese proponents with the following 'a'-versus-'b' comparison: (a) When people and organizations focus primarily on quality, defined by the following ratio, $Quality\ = \frac{Results\ of\ work\ efforts}{Total\ costs}$ quality tends to increase and costs fall over time. (b) However, when people and organizations focus primarily on costs (often dominant/typical human behavior), costs (due to not minimizing waste, ignoring amount of rework occurring, taking staff for granted, not rapidly resolving disputes, and failing to notice lack of product improvement—plus, over time, loss of customer loyalty) tend to rise and quality declines over time. ### The Deming System of Profound Knowledge™ Edit "The prevailing style of management must undergo transformation. A system cannot understand itself. The transformation requires a view from outside. The aim of this chapter is to provide an outside view—a lens—that I call a system of profound knowledge. It provides a map of theory by which to understand the organizations that we work in. "The first step is transformation of the individual. This transformation is discontinuous. It comes from understanding of the system of profound knowledge. The individual, transformed, will perceive new meaning to his life, to events, to numbers, to interactions between people. "Once the individual understands the system of profound knowledge, he will apply its principles in every kind of relationship with other people. He will have a basis for judgment of his own decisions and for transformation of the organizations that he belongs to. The individual, once transformed, will: • Set an example; • Be a good listener, but will not compromise; • Continually teach other people; and • Help people to pull away from their current practices and beliefs and move into the new philosophy without a feeling of guilt about the past." Deming advocated that all managers need to have what he called a System of Profound Knowledge, consisting of four parts: 1. Appreciation of a system: understanding the overall processes involving suppliers, producers, and customers (or recipients) of goods and services (explained below); 2. Knowledge of variation: the range and causes of variation in quality, and use of statistical sampling in measurements; 3. Theory of knowledge: the concepts explaining knowledge and the limits of what can be known (see also: epistemology); 4. Knowledge of psychology: concepts of human nature. Deming explained, "One need not be eminent in any part nor in all four parts in order to understand it and to apply it. The 14 points for management in industry, education, and government follow naturally as application of this outside knowledge, for transformation from the present style of Western management to one of optimization." "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. A psychologist that possesses even a crude understanding of variation as will be learned in the experiment with the Red Beads (Ch. 7) could no longer participate in refinement of a plan for ranking people."[18] The Appreciation of a system involves understanding how interactions (i.e. feedback) between the elements of a system can result in internal restrictions that force the system to behave as a single organism that automatically seeks a steady state. It is this steady state that determines the output of the system rather than the individual elements. Thus it is the structure of the organization rather than the employees, alone, which holds the key to improving the quality of output. The Knowledge of variation involves understanding that everything measured consists of both "normal" variation due to the flexibility of the system and of "special causes" that create defects. Quality involves recognizing the difference in order to eliminate "special causes" while controlling normal variation. Deming taught that making changes in response to "normal" variation would only make the system perform worse. Understanding variation includes the mathematical certainty that variation will normally occur within six standard deviations (thus six sigma: the symbol for standard deviation) of the mean. The System of Profound Knowledge™ is the basis for application of Deming's famous 14 Points for Management, described below. ### Deming's 14 points Edit Deming offered fourteen key principles for management for transforming business effectiveness. In summary: 1. Create constancy of purpose toward improvement of a product and service with a plan to become competitive and stay in business. Decide to whom top management is responsible. 2. Adopt the new philosophy. We are in a new economic age. We can no longer live with commonly accepted levels of delays, mistakes, defective materials, and defective workmanship. 3. Cease dependence on mass inspection. Require, instead, statistical evidence that quality is built in. (prevent defects instead of detect defects.) 4. End of the practice of awarding business on the basis of price tag. Instead, depend on meaningful measures of quality along with price. Eliminate suppliers that cannot qualify with statistical evidence of quality. 5. Find Problems. It is a management’s job to work continually on the system (design, incoming materials, composition of material, maintenance, improvement of machine, training, supervision, retraining) 6. Institute modern methods of training on the job 7. The responsibility of the foreman must be to change from sheer numbers to quality… [which] will automatically improve productivity. Management must prepare to take immediate action on reports from the foremen concerning barriers such as inherent defects, machines not maintained, poor tools, and fuzzy operational definitions. 8. Drive out fear, so that everyone may work effectively for the company. 9. Break down barriers between departments. People in research, design, sales and production must work as a team to foresee problems of production that may be encountered with various materials and specifications. 10. Eliminate numerical goals, posters, slogans for the workforce, asking for new levels of productivity without providing methods. 11. Eliminate work standards that prescribe numerical quotas. 12. Remove barriers that stand between the hourly worker and his right of pride of workmanship. 13. Institute a vigorous program of education and retraining. 14. Create a structure in top management that will push every day on the above 13pts. ### Seven Deadly Diseases Edit The Seven Deadly Diseases: 1. Lack of constancy of purpose. 2. Emphasis on short-term profits. 3. Evaluation by performance, merit rating, or annual review of performance. 4. Mobility of management. 5. Running a company on visible figures alone. 6. Excessive medical costs. 7. Excessive costs of warranty, fueled by lawyers who work for contingency fees. A Lesser Category of Obstacles: 1. Neglecting long-range planning. 2. Relying on technology to solve problems. 3. Seeking examples to follow rather than developing solutions. 4. Excuses, such as "Our problems are different." ## Quotations and concepts Edit In his later years, Dr. Deming taught many concepts, which he emphasized by key sayings or quotations that he repeated. A number of these quotes have been recorded.[19] Some of the concepts might seem to be oxymorons or contradictory to each other; however, the student is given each concept to ponder its meaning in the whole system, over time. Some phrases below might appear repetitious, but consider not only the phrase, but also the situation when applied: • "There is no substitute for knowledge." This statement emphasizes the need to know more, about everything in the system. It is considered as a contrast to the old statement, "There is no substitute for hard work" by Thomas Alva Edison (1847–1931). Instead, a small amount of knowledge could save many hours of hard work, just as knowing a password could save hours trying to remember or getting the password reauthorized or reset. • "The most important things cannot be measured." The issues that are most important, long term, cannot be measured in advance. However, they might be among the factors that an organization is measuring, just not understood as most important at the time. • "The most important things are unknown or unknowable." The factors that have the greatest impact, long term, can be quite surprising. Analogous to an earthquake that disrupts service, other "earth-shattering" events that most affect an organization will be unknown or unknowable, in advance. Other examples of important things would be: a drastic change in technology, or new investment capital. • "Experience by itself teaches nothing."[19] This statement emphasizes the need to interpret and apply information against a theory or framework of concepts that is the basis for knowledge about a system. It is considered as a contrast to the old statement, "Experience is the best teacher" (Dr. Deming disagreed with that). To Dr. Deming, knowledge is best taught by a master who explains the overall system through which experience is judged; experience, without understanding the underlying system, is just raw data that can be misinterpreted against a flawed theory of reality. Deming's view of experience is related to Shewhart's concept, "Data has no meaning apart from its context" (see Walter A. Shewhart, "Later Work"). • "By what method?... Only the method counts."[19] When information is obtained, or data is measured, the method, or process used to gather information, greatly affects the results. For example, the "Hawthorne effect" showed that people just asking frequently for opinions seemed to affect the resulting outcome, since some people felt better just being asked for their opinion. Dr. Deming warned that basing judgments on customer complaints alone ignored the general population of other opinions, which should be judged together, such as in a statistical sample of the whole, not just isolated complaints: survey the entire group about their likes and dislikes. The extreme complaints might not represent the attitudes of the whole group. Similarly, measuring or counting data depends on the instrument or method used. • "You can expect what you inspect." Dr. Deming emphasized the importance of measuring and testing to predict typical results. If a phase consists of inputs + process + outputs, all 3 are inspected to some extent. Problems with inputs are a major source of trouble, but the process using those inputs can also have problems. By inspecting the inputs and the process more, the outputs can be better predicted, and inspected less. Rather than use mass inspection of every output product, the output can be statistically sampled in a cause-effect relationship through the process. • "Special Causes and Common Causes": Dr. Deming considered anomalies in quality to be variations outside the control limits of a process. Such variations could be attributed to one-time events called "special causes" or to repeated events called "common causes" that hinder quality. • Acceptable Defects: Rather than waste efforts on zero-defect goals, Dr. Deming stressed the importance of establishing a level of variation, or anomalies, acceptable to the recipient (or customer) in the next phase of a process. Often, some defects are quite acceptable, and efforts to remove all defects would be an excessive waste of time and money. • The Deming Cycle (or Shewhart Cycle): As a repetitive process to determine the next action, the Deming Cycle describes a simple method to test information before making a major decision. The 4 steps in the Deming Cycle are: Plan-Do-Check-Act (PDCA), also known as Plan-Do-Study-Act or PDSA. Dr. Deming called the cycle the Shewhart Cycle, after Walter A. Shewhart. The cycle can be used in various ways, such as running an experiment: PLAN (design) the experiment; DO the experiment by performing the steps; CHECK the results by testing information; and ACT on the decisions based on those results. • Semi-Automated, not Fully Automated: Dr. Deming lamented the problem of automation gone awry ("robots painting robots"): instead, he advocated human-assisted semi-automation, which allows people to change the semi-automated or computer-assisted processes, based on new knowledge. Compare to Japanese term 'jidoka' (which can be loosely translated as "automation with a human touch"). • "The problem is at the top; management is the problem." [18] Dr. Deming emphasized that the top-level management had to change to produce significant differences, in a long-term, continuous manner. As a consultant, Deming would offer advice to top-level managers, if asked repeatedly, in a continuous manner. • "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.)" [18] • "A system must be managed. It will not manage itself. Left to themselves in the Western world, components become selfish, competitive. We can not afford the destructive effect of competition." [18] • "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." [18] • "The worker is not the problem. The problem is at the top! Management!" [20] 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." [18] • "They realized that the gains that you get by statistical methods are gains that you get without new machinery, without new people. Anybody can produce quality if he lowers his production rate. That is not what I am talking about. Statistical thinking and statistical methods are to Japanese production workers, foremen, and all the way through the company, a second language. In statistical control, you have a reproducible product hour after hour, day after day. And see how comforting that is to management, they now know what they can produce, they know what their costs are going to be." [21] • "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!" [21] • "What is the variation trying to tell us about a process, about the people in the process?" [18] Dr. Shewhart created the basis for the control chart and the concept of a state of statistical control by carefully designed experiments. While Dr. Shewhart drew from pure mathematical statistical theories, he understood that data from physical processes never produce a "normal distribution curve" (a Gaussian distribution, also commonly referred to as a "bell curve"). He discovered that observed variation in manufacturing data did not always behave the same way as data in nature (Brownian motion of particles). Dr. Shewhart concluded that while every process displays variation, some processes display controlled variation that is natural to the process, while others display uncontrolled variation that is not present in the process causal system at all times.[22] Dr. Deming renamed these distinctions "common cause" for chance causes and "special cause" for assignable causes. He did this so the focus would be placed on those responsible for doing something about the variation, rather than the source of the variation. It is top management’s responsibility to address "common cause" variation, and therefore it is management’s responsibility to make improvements to the whole system. Because "special cause" variation is assignable, workers, supervisors or middle managers that have direct knowledge of the assignable cause best address this type of specific intervention.[7] • (Deming on Quality Circles) "That's all window dressing. That's not fundamental. That's not getting at change and the transformation that must take place. Sure we have to solve problems. Certainly stamp out the fire. Stamp out the fire and get nowhere. Stamp out the fires puts us back to where we were in the first place. Taking action on the basis of results without theory of knowledge, without theory of variation, without knowledge about a system. Anything goes wrong, do something about it, overreacting; acting without knowledge, the effect is to make things worse. With the best of intentions and best efforts, managing by results is, in effect, exactly the same, as Dr. Myron Tribus put it, while driving your automobile, keeping your eye on the rear view mirror, what would happen? And that's what management by results is, keeping your eye on results." [2] • "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." [18] This statement emphasizes the need for theory of knowledge (see: epistemology, Shewhart cycle, C. I. Lewis). • "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."[18] These statements emphasize the need to interpret information using a theory or framework of concepts for learning to take place, theory of knowledge. Deming's view of experience is related to Shewhart's concept, "Data has no meaning apart from its context" (see Walter A. Shewhart, "Later work"). • "The most important figures that one needs for management are unknown or unknowable (Lloyd S. Nelson, director of statistical methods for the Nashua corporation), but successful management must nevertheless take account of them." [23] Deming realized that many important things that must be managed couldn’t be measured. Both points are important. One, not everything of importance to management can be measured. And two, you must still manage those important things. Spend$20,000 training 10 people in a special skill. What's the benefit? "You'll never know," answered Deming. "You'll never be able to measure it. Why did you do it? Because you believed it would pay off. Theory." Dr. Deming is often incorrectly quoted as saying, "You can't manage what you can't measure." In fact, he stated that one of the seven deadly diseases of management is running a company on visible figures alone.
• "By what method?" [19] When information is obtained, or data is measured, the method, or process used to gather information, affects the results. Dr. Deming warned that basing judgments on customer complaints alone ignored the general population of other opinions, which should be judged together, such as in a statistical sample of the whole (Sampling (statistics)). Changing the method changes the results. Aim and method are essential. An aim without a method is useless. A method without an aim is dangerous. It leads to action without direction and without constancy of purpose. Deming used an illustration of washing a table to teach a lesson about the relationship between purpose and method. If you tell someone to wash a table, but not the reason for washing it, they cannot do the job properly (will the table be used for chopping food or potting plants?). That does not mean just giving the explanation without an operational definition. The information about why the table needs to be washed, and what is to be done with it, makes it possible to do the job intelligently.
