How Deming met Kaoru Ishikawa after World War II


Deming first visited Japan in 1947 to assist SCAP [Supreme Commander of the Allied Powers] in surveys of housing, agriculture and unemployment. At the same time, the communications section of SCAP was teaching Japanese industrialists (particularly in electronics) the fundamentals of statistical control of quality. While the techniques taught were based on those he and others had developed through the 1920s and 1930s, he was not involved in that initial teaching.

The managing director of JUSE [Union of Japanese Scientists and Engineers] at that time was Kenichi Koyanagi. It was he who asked Deming to speak at a dinner in Tokyo in July 1950. Prior to his talks to management, Deming also met for planning sessions with Kaoru Ishikawa several times. Ishikawa was a highly influential Japanese industrialist. He was president of JUSE, but his real power came from his leadership of the large industrial coalition. It was Ishikawa who issued the invitations to 21 top industrial leaders to listen to Deming. The invitations were not ignored.

The Japanese knew they were dependent on international trade to fuel their recovery. They were already being taught quality-control tools and techniques and had a well-educated and practiced workforce, so that is not what Deming was there to teach.

Ishikawa wanted Deming to give a message that went beyond the techniques of SQC [statistical quality control] and shop-floor tools for improvement. He wanted industrial leaders to be exposed to a global strategy for Japanese industry as a whole. By what method would Japan pull itself out of its crisis?

He asked Deming to lecture on the responsibilities of management. And Deming did just that, both at the dinner and at the Mount Hakone conference center a few weeks later. Deming's own summary of what he taught them can be found in a book about him, The World of W Edwards Deming, written by his assistant Cecelia Killian, who worked with him for 40 years. This correspondent also subsequently obtained a transcript of his talk in Mount Hakone.

He told the assembled industry heads about the new economic age that was just beginning and what they would have to do to survive and flourish in this new global economic environment. He told them about the chain reaction that occurs when one becomes totally focused on quality improvement.

This is a key lesson because with attention to quality, the company begins a journey on a "virtuous circle" of simultaneously improving quality and lowering costs. As quality improves, there are less rework, scrap and waste of all kinds. As products become more attuned to customers' needs, there is less effort spent producing items people don't want. Costs go down. Quality improves. Thus paying attention to quality becomes the primary competitive strategy. Understanding this is vitally important.

I remember vividly a videotaped interview of Deming shot when he was in his late 80s. He says quite clearly, "It's very simple, really. Pay attention to quality first. Quality goes up and costs go down. You will have less waste, less rework, less scrap. You enter the market with better and better quality and lower and lower cost. You will capture the market." In 1950, he was prophetic.

He proposed that the Japanese use market research. It was an emerging field in the United States and almost unheard of in Japan. He told them they would have to travel to where the customer was to do this. Deming had gained expertise in sampling when he worked for the US Bureau of the Census, and he applied that statistical expertise to understand customers better.

Think of General Motors' blunder of trying to sell the Hummer and Toyota's success with its hybrid car to understand the importance of this lesson. Quality must begin with the customer.

Another main lesson Deming taught was the need for top management to take personal responsibility for the quality of the product. It is not enough to teach the tools (eg statistical quality control - SQC) of quality improvement, it is also necessary to create an environment where they can be used. Only management can do that. Managers must understand that this is their responsibility and theirs alone.

Without long-term consistent and insistent leadership on quality from management, Japan would not find its way out of the crisis. An improvement here and there would not be enough to make significant change.

Deming taught the Japanese the importance of seeing improvement, product design, and manufacturing as never-ending processes. He introduced an early version of what has become widely known as the "plan, do, study, act" (PDSA or sometimes PDCA, for "plan, do, check and act") cycle. He called it the Shewhart cycle as its origins were derived from Walter Shewhart's early work at Bell Labs. Again this is critical.

PDSA is roughly analogous to the scientific method. In that method, one has a theory (or hypothesis), and he puts it to the test; he studies the results and takes action based on those results. This is the road to scientific learning. PDSA is the road to organizational learning. Peter Senge wrote about the "learning organization" in 1990. Deming taught the method to become a learning organization in 1950.

Much of modern-day competitiveness is based on management accelerating the rate at which improvements are made. The key to this is effective means of learning. Time spent on the superstition of "managing by the seat of the pants" is often waste.

Deming advised them that a supplier is a partner. Relationships with suppliers must be based on cooperation and trust. Adversarial relationships result in waste. Supplier relationships based on Deming's teachings change fundamentally and, even better, both supplier and customer win.

Deming showed how customers and suppliers are brought into, and become part of, the production system. Systems thinking is the key. The supplier-producer-customer network works together as a system.

Any country or industry that follows these basic principles will become competitive in the global economy and begin to gain share in the markets in which it does business. Speculation is not required. As we say in statistics, "The data are in."

The methods outlined above that Deming taught are not difficult to understand, nor are they proprietary. Anyone can do it. But it is not so easy to do. Change is required. For that reason, those who do begin this journey of continual improvement and competitive gain will tend to gain a consistent advantage of those who squander the opportunity.

In his 1986 book Out of the Crisis, Deming asks (rhetorically), "Need any country be poor?" For any country willing to modify Deming's fundamental principles to suit its own culture and population, the answer may well be "No."

How General MacArthur allowed Japan to become First Quality Industrial Nation - part I


This is not a story you expect. And it's the sort of lesson that's so important that we as a society have already forgotten it.

Homer Sarasohn, who lives with his wife in a retirement complex in Scottsdale, Arizona, is a gentle man with an owl-like face, Sarasohn never planned to go to Japan. He really wanted to be a gynecologist, but couldn't afford to go to medical school during the Depression. So Sarasohn fell back on his undergraduate physics degree, and went to work before the war designing radio transmitters. When the Second World War came along, he served as a paratrooper, then later resumed his radio work, joining the staff of the MIT Radiation Laboratory.

The Rad Lab, as it was called, was the major U.S. development center for Radar during the war, and it was Sarasohn's job to take laboratory prototypes of new radar equipment and turn them into products that could be mass produced by the radio manufacturers of the day. He was still working at the Rad Lab in 1946, when a telegram came from Washington, summoning him to Tokyo. The telegram said he was wanted by General Douglas MacArthur, head of the occupation forces in Japan.

"I thought it was a joke," Sarasohn said. He was 29 years old.

MacArthur's headquarters was divided into several sections. Each section served as a branch of the Japanese government, though with an American administrator in each leadership role. The U.S. government was MacArthur's nominal model, though he adapted it in places to suit the very different needs of both Japanese society and his own military background. There was no true president, for example; MacArthur played, instead, the role of emperor, which suited him.

When he got to Japan, Sarasohn was made chief of the Industry Branch within the Civil Communications Section. That meant he was in charge of rebuilding the communication infrastructure of Japan. MacArthur wanted to use radio as a tool of occupation — to communicate directly with the people of Japan — and that meant setting-up transmitters, as well as building hundreds of thousands of radio receivers. Radios would be the first appliances available to the public in post-war Japan.

"There were fewer than 100 people in the Civil Communications Section, and none of us knew anything about Japan," Sarasohn said. "American bombing had laid bare the country. There were refugees everywhere. The factories were all gone. What electronics production equipment hadn't been destroyed was dispersed to the countryside. We had to find equipment and people with experience to run it, then set up factories wherever we could. The easiest way to get up and running was to bring back to life the companies that had been operating during the war — NEC, Matsushita, Furukawa, Fujitsu, Toshiba, and others. Within a year we got them organized in a primitive way."

MacArthur had abolished the Zaibatsu — the confederations of companies that had dominated the pre-war Japanese economy. These groups, the remnants of which survive today in the form of Japan's enormous trading conglomerates, created domestic cartels, manipulated supplies and prices, and generally established the long Japanese tradition of building a robust economy on the backs of submissive consumers. MacArthur blamed the war on the Zaibatsu and its leaders, who he banned from participating in their old companies, taking virtually all top managers out of the labor pool (they later returned, following the end of U.S. occupation of Japan, and ex-Zaibatsu leaders were mainly responsible for Japan's economic resurgence in the 1960s). With all the leaders gone, Sarasohn had to promote middle managers, when he could find them, into the top jobs.

Those were the days of vacuum tube radios, and when vacuum tube production finally began in the makeshift plants, the American was appalled to see that yields were typically less than 10 percent. Ninety percent of the vacuum tubes would not work. To the Japanese running the factories, this was no surprise, nor was it a cause for concern; it had always been this way, even before the war.

"The Japanese had no sense of quality," Sarasohn said. "With the exception of the Zero fighter and some aircraft engines, their designs were bad and their manufactured goods were shoddy. Having come from the Rad Lab, I was particularly appalled to see the primitive nature of Japanese naval radar. Their vacuum tubes were bad and the radios were even worse, since each was hand-wired by untrained, often unsupervised, workers. They produced goods in mass quantities, ignoring quality. The factories were filthy, and with the exception of some technology picked up from Germany early in the war, most of their production techniques dated from the Meiji Restoration of 1868."

Sarasohn called in the plant managers, asking them to identify one problem they could work on to improve quality.

"There was utter silence," he said. "They were not expected to make meaningful contributions to their companies in this sense."

Eventually, the managers began to talk with each other, while Sarasohn waited. According to the translator, they were trying to decide what answer to give that would most please the American. That was when Homer Sarasohn decided to become the Japanese electronics czar. "I had to become a dictator to get anything done," he said. "It's part of the Japanese psyche that they follow the leader. The expression they used then translated to 'pay the man in power,' which was a holdover from the culture of submission popular during the Tokagawa era of the 19th century. If I was going to get the industry back on its feet, I would have to take complete charge."

In order to play his dictator role, Sarasohn first had to learn Japanese. "Our translators were Nisei GIs, mainly farm-boys from Hawaii," he said. "They couldn't understand the technical materials they were being asked to translate. Worse still, they were distrusted by the native Japanese, who saw them as traitors since they were not really Japanese and weren't loyal to the emperor. It was easier for me to rule directly as a representative of the conquering horde than to try to rule through translators. For the first time in its history, invincible Japan had been conquered, the emperor had been forced to say he was not a god, and I represented the force that had made those changes happen. My power was unquestioned."

Frustrated with Japanese language courses offered by MacArthur's staff, the American moved-in with a Japanese family, embracing their culture, and living as a Japanese until 1950.

Under Sarasohn's control, the Japanese electronics industry began to make slow progress. Yields rose over time as new production methods were adopted, eventually reaching around 75 percent for vacuum tubes (Sylvania, which set the world standard for vacuum tubes, had an 85 percent yield at the time). But there still wasn't a deep understanding of the need for quality.

"I remember visiting the Hirakawa Electric Company in Osaka (the company is today called Sharp Electronics). The manager wanted to show me that he understood my lectures about having a clean workplace," Sarasohn said. "He had hired a man specifically to keep the place clean. We found him in one of the big assembly areas. This fellow had a stick with a string coming from the end of it, and on the end of the string were a couple of pieces of ribbon. He was going around the assembly benches, flicking this stick, using the ribbons to push the dust around a little. The plant manager looked on proudly, thinking that his man was 'cleaning' the plant, and that I would be impressed."

On another occasion, Sarasohn made a surprise visit to the Tokyo Communication Engineering Company. He'd given the small company an important job, building a special piece of electronic equipment, but the project was long overdue. Travelling alone across Tokyo, he appeared without warning at the electronics factory, demanding to see the equipment he'd ordered. The owners were absent, parts were scattered everywhere and covered with dust. The special project, a radio station studio mixing console, lay about in pieces, barely begun. Furious with what he saw, Sarasohn exited without a word, leaving the workers in disgrace.

When they heard about the disastrous visit, the two founders of the Tokyo Communication Engineering Company hurried across the city to mollify Sarasohn. Their business was only a couple years old, and they didn't want its history to end that day.

The issue was quality. The plant was a mess. The special project was not only unfinished, the quality of work that its parts displayed was bad. Sarasohn gave them one last chance. "I told them to either mend their ways or lose their jobs," he said.

The Tokyo Communication Engineering Company later changed its name to Sony Corporation. The two men who came to plead for the survival of their company were Sony co-founders Masaru Ibuka and Akio Morita.

When the Second World War ended, American leaders thought their occupation of Japan might last forever. But by 1949, it was clear to Sarasohn that the Korean War was coming, and that the American occupation of Japan would soon end. If his work was to survive, he had to find a way of permanently instilling in Japanese industry some regard for quality.

First, Sarasohn set up the Electrical Test Laboratory, which was used to test prototype radios and other electrical gear before they could be approved for production. Later, random samples of the same goods would be taken off production lines for further testing to guarantee that quality remained at an acceptable level. If quality dropped, the production lines would be shut down, tying the success of management directly to its control of quality. The people in charge were thus personally committed to product quality, and could not delegate this responsibility.

The Electrical Test Laboratory still operates in Japan, fulfilling the same function set up by Homer Sarasohn in 1949. It serves new functions that Sarasohn could never have predicted, too, including acting as a barrier for the entry of American electronic goods that must first pass a tedious battery of superfluous tests before they are allowed in the country. Every electric fan, stereo component, and room air conditioner must be tested again in a Japanese facility, despite carrying Federal Communications Commission or Underwriters' Laboratory approvals.

After he set up the Electrical Test Laboratory, Sarasohn wanted to develop a course in American management techniques specifically for Japanese plant managers. But some members of the occupation forces opposed spreading U.S. production know-how to the Japanese.

The issue was decided in a 20-minute presentation before General MacArthur. The General had long before stopped following the letter of his original orders, which told him specifically to "not assume any responsibility for the economic rehabilitation or strengthening of the Japanese economy." Sarasohn argued that without better management, Japan would be a long-term drain on U.S. taxpayers. His opposition, the head of the Economics and Social Section, argued that the program Sarasohn was proposing could turn Japan into an economic monster that would threaten the U.S. in world markets.

"Go do it," MacArthur said casually on his way out the door, changing the course of world history.

History of Total Quality Management

After World War II, the U.S. was the only major power with an intact economy. Deming and Juran found their quality improvement theories irrelevant to U.S. business leaders. They were interested in quantity, not quality.

Deming found a more appreciative audience in Japan, where he was conducting postwar census work. He was invited to speak about his views during a now-famous dinner in the early 1950's.

Shortly after, Dr. Deming predicted in the early 1950's that the Japanese industry would become a world-class force equal to any other country. Everyone around the world laughed. The Japanese didn't laugh . They worked hard to apply the lessons learned. Henry Ford's book on manufacturing (written decades earlier) became a Japanese best seller. There was a weekly radio program that trained workers, lead hands, supervisors, and managers on statistics and Dr. Deming's methods. It became a national hit in most Japanese homes. Drs. Deming and Juran because celebrities in constant demand as speakers and consultants.

Decades later, the Emperor of Japan awarded Dr. Deming with the highest Japanese award for a civilian in recognition for his decades of hard work and leadership he gave to the Japanese people and their government.

The Japanese business leaders listened, the rest is history.

Below is a 30 minute video about Deming's crucial actor in the History of Total Quality Management.
