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.

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.

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.

The aim of this book is to try to explain to top management of America that their job is to improve competitive position. One need not be an economist to understand from the papers that many American products are not competitive at home or abroad, lost to foreign invasion, causing unemployment at home. Failure of management to plan for the future and to foresee problems has nurtured waste of manpower, of materials and of machine time, all of which raise the manufacturers costs and the price the purchaser must pay. The consumer is not always willing to subsidize this waste.
