Quotations

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! The MIT Press

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. (pg. 2)

Defects are not free. Somebody makes them, and gets paid for making them. (pg. 11)

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. (pg. 99)

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 we taught. Pleasant dreams. The workers are handicapped by the system, and the system belongs to the management. (pg. 134)

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. (pg. 139)

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... (pg. 175)
