The New Economics for Industry, Government, Education

W. Edwards Deming, a statistician and management consultant whose teachings on quality transformed Japanese industry beginning in 1950, presents in this 1994 work a comprehensive framework for replacing the prevailing style of Western management with one built on cooperation, systems thinking, and what he calls Profound Knowledge. Writing for managers, educators, and government leaders, Deming argues that hard work and best efforts, without guidance from new knowledge, only deepen the problems organizations face.

Deming opens with a diagnosis of economic decline. The United States once produced half the world's manufactured goods (around 1910) and enjoyed a postwar advantage as the only industrial region operating at full capacity, but by the mid-1950s, Japanese goods of steadily improving quality began entering American markets. Deming identifies quality as the central problem, defining it simply: A product or service possesses quality if it helps somebody and enjoys a good, sustainable market. He argues that customers do not invent new products; innovation comes from producers who predict and anticipate needs. No customer asked for electric lights, the telephone, or the integrated circuit. Zero defects alone do not guarantee survival, since a plant can produce flawless work yet close if the product loses its market. Quality, Deming insists, is determined by top management and cannot be delegated. He illustrates with the Sacred Heart League, a charitable organization near Memphis: Flawless operations in folding, addressing, and mailing are meaningless if the message inside the envelope fails to generate donations.

The second chapter catalogs what Deming calls the heavy losses of prevailing management. He critiques short-term thinking, the ranking of people and divisions, incentive pay, management by objective (M.B.O.), numerical goals without methods, and purchasing at lowest bid. For ranking, he presents a simple equation showing that individual contribution cannot be separated from the system's effect, making the merit system mathematically insoluble. He cites the Pygmalion effect, a psychological phenomenon in which initial ratings become self-fulfilling, to argue that ranking entrenches performance rather than improving it. Numerical goals without methods produce distortion: a 1992 Sears Roebuck scandal saw auto service agents cheating customers to meet targets, and a bank agent met an $83 million monthly lending quota by making bad loans. A summary table reveals that 97 percent of potential gains remain untouched in companywide systems such as personnel, training, and purchasing, while only 3 percent have received attention on the shop floor. Deming states that 94 percent of troubles belong to the system, which is management's responsibility, while only 6 percent stem from special causes.

Chapter 3 introduces the theory of a system, defined as a network of interdependent components working together toward an aim. Without an aim, there is no system. The recommended aim is for everybody to gain over the long term: stockholders, employees, suppliers, customers, community, and the environment. Deming presents the flow diagram he used in Japan beginning in 1950, showing production flowing from incoming materials through design, production, inspection, and distribution to the consumer, with a feedback loop through consumer research. He contrasts this with the traditional organizational pyramid, which encourages employees to please the boss rather than serve the customer. Multiple examples illustrate systemic destruction: an engineer's proposal to save $50 overall was rejected because it would raise one division's costs; a travel department booked a cheap flight requiring a traveler to leave home at 12:30 a.m., leaving her unfit for work. Deming argues that competitors should cooperate to expand markets rather than fight over share, and demonstrates quantitatively how departments operating as independent profit centers produce net losses, while management that optimizes the whole company generates gains distributed equally.

Chapter 4 presents the System of Profound Knowledge, a four-part lens for understanding organizations. Its components are appreciation for a system, knowledge about variation, theory of knowledge, and psychology. Under variation, Deming distinguishes common causes (inherent in the system) from special causes (attributable to something external to normal operation) and identifies two costly mistakes: treating common-cause variation as special, and treating special-cause variation as common. Under theory of knowledge, he argues that management is prediction and that knowledge requires theory subject to systematic revision. He uses the story of the rooster Chanticleer, who believed his crowing caused the sunrise until the morning he forgot and the sun rose anyway, to show that without theory there is no learning. Under psychology, he argues that ranking and merit pay crush intrinsic motivation, introducing the phenomenon of overjustification: a boy who voluntarily washed dishes stopped entirely once his mother paid him a quarter for the task.

A chapter on leadership defines a leader as someone who accomplishes transformation through knowledge, personality, and persuasive power. Deming illustrates with Morris H. Hansen, who at age 24 in 1935, working as a statistical clerk at the Bureau of the Census, designed a random sample of 52 postal routes to study unemployment. Congress accepted Hansen's results while ignoring a far larger but error-ridden complete census, because Hansen convinced key people in power who understood his theory.

Chapter 6 outlines a new role for managers. Deming presents a diagram showing forces of destruction, from grades in school through merit systems and incentive pay, that progressively crush innate motivation and curiosity. He lists 14 characteristics of the transformed manager, including understanding the system's aim, coaching rather than judging, and creating trust. He introduces the PDSA (Plan-Do-Study-Act) Cycle for learning and improvement: plan a change, carry it out on a small scale, study the results, then adopt, abandon, or repeat. He calls for abolishing grades in school and forced ranking, arguing that these practices produce humiliation and artificial scarcity.

The Red Beads experiment in Chapter 7 uses 4,000 wooden beads (800 red, 3,200 white) and a paddle with 50 depressions. Workers scoop beads under rigid procedures while the foreman awards merit raises, imposes probation, and sets numerical goals. The data show a process in statistical control: All variation comes from common causes. When the three "best" workers are retained, their subsequent performance is no better, demonstrating that past results in a stable system do not predict future performance. The lesson is that ranking rewards or punishes the system, not the individual.

Chapter 8 explains Walter Shewhart's control chart, developed at the Bell Telephone Laboratories, as a tool for distinguishing common from special causes. Deming emphasizes that specification limits (what is desired) differ from control limits (what the process is doing) and applies the framework to fires, highway accidents, and malpractice suits. The funnel experiment in Chapter 9 demonstrates that tampering with a stable process makes results worse. Four rules for aiming a funnel at a target produce progressively worse patterns: leaving the funnel fixed is best, while compensating for each error produces expanding variance, oscillations, or indefinite drift.

The final chapter offers applied lessons in variation. Deming introduces the loss function, a framework showing that loss increases gradually as output deviates from the target value, not abruptly when it crosses specification limits. Genichi Taguchi termed the resulting waste "loss to society" (218). Deming demonstrates that loss is minimized when production is centered on the nominal value, making the center of distribution more important than dispersion alone. He concludes that conformance to specifications, zero defects, and similar measures "all miss the point" (226).

An appendix on purchasing argues for long-term, single-supplier relationships, reasoning that deep cooperation optimizes the system for both parties. Deming lists criteria for supplier selection and advises that the single supplier, knowing competitors better than the customer does, should prearrange emergency backup with a competitor.
