In his last interview, Dr. W. Edwards Deming shared his thoughts on quality, management, innovation, and more.
Editor's Note: IndustryWeek caught up with W. Edwards Deming on Oct. 23, 1993, in what would be his last interview. In a series of articles, IndustryWeek is presenting his timeless words. Don't miss Part 1 of IW's conversation with Dr. Deming.
IW: Quoting from your book [The New Economics (1993, MIT Center for Advanced Engineering Study)], you say, "You can learn a lot about ice and know nothing about water.' What does that mean?
Dr. Deming: It means you can understand your present job and understand it very well. But what is the result of hard work and best efforts? What they do is only to dig deeper the pit that we are in. But they will not dig us out of the pit, only dig it deeper, make it more difficult to get out of. To get out of the pit we require an outside view. No chance from the inside. A system cannot understand itself. Understanding comes from outside. An outside view provides a lens for examination of our present actions, policies. Outside view is the aim of my chapter four [The New Economics] on profound knowledge. Knowledge from outside is necessary. Knowledge from outside gives us a view of what we're doing, what we might do, a road to improvement, continual improvement.
IW: Is that view provided by other people?
Dr. Deming: It's a very good idea. Knowledge will not come from a committee inside. How could a committee produce new knowledge? The view must come from the outside. A committee in a company can hardly stumble onto it. You enlarge the committee, bigger and bigger. That still doesn't do it. Enlarge the committee, make the committee everybody. Popular vote. Will popular vote provide the right answer? Maybe, by accident. How else could it? It's frightening. Popular vote does not solve our problems. Popular vote makes everybody responsible for the results. Let's work on it, do our best, within a framework. We could do that. Far better, more trustworthy, is an outside view. A new way of looking at things. It is only by that outside view that we get ahead, I believe.
IW: You are referring to your system of profound knowledge.
Dr. Deming: Yes. By profound knowledge, I mean knowledge from outside.
IW: Your system of profound knowledge has four components: appreciation for a system, knowledge of variation, theory of knowledge, and psychology. Please elaborate a bit on each of the four components.
Dr. Deming: Well, the theory of psychology. How could anyone learn about psychology of people, of individuals, without knowledge of variation? What do the variations mean between people, between groups? How can we capitalize on those differences? How can we assist people, because they have those differences? A good manager of people capitalizes on the family background, abilities, capabilities, and hopes of his people. He tries to give everybody a chance to take pride in his work, joy in his work. Why is it that your company is not as good as the people in it? Because the management of the company may not be good at finding the right job for the right people, or because interactions between people are not good. A company could put a top man at every position and be swallowed by a competitor with people only half as good, but who are working together.
A good manager of people capitalizes on the family background, abilities, capabilities, and hopes of his people. He tries to give everybody a chance to take pride in his work, joy in his work."
IW: One of the components of your system of profound knowledge is theory of knowledge. Please comment on that.
Dr. Deming: Any decision that management makes, that anybody makes for himself or for other people, is prediction. The simplest plan is prediction, with a chance to be wrong. How may I get home tonight? I predict that my automobile will start and run, or that the bus will come, or that the train will come. I make plans. Those plans are predictions. Management is prediction; our lives are prediction. We predict what will happen. We try to choose a course of action that will react in favor of us. That's our aim. We predict the consequence of actions.
