“I cannot say that any one agreed with me. The selling people could not of course see the advantages that a single model would bring about in production. More than that, they did not particularly care. They thought that our production was good enough as it was and there was a very decided opinion that lowering the sales price would hurt sales.”— Henry Ford

“On January 1st we had $20,000,000. On April 1st we had $87,300,000, or $27,300,000 more than we needed to wipe out all our indebtedness. That is what boring into the business did for us! This amount came to us in these items: Cash on hand, January $20,000,000; Stock on hand turned into cash, January 1 to April 1 $24,700,000; Speeding up transit of goods released $28,000,000; Collected from agents in foreign countries $3,000,000; Sale of by-products $3,700,000; Sale of Liberty Bonds $7,900,000.”

“Along about April 1, 1913, we first tried the experiment of an assembly line. We tried it on assembling the flywheel magneto. We had previously assembled the fly-wheel magneto in the usual method. With one workman doing a complete job he could turn out from thirty-five to forty pieces in a nine-hour day, or about twenty minutes to an assembly. What he did alone was then spread into twenty-nine operations; that cut down the assembly time to thirteen minutes, ten seconds.”— Henry Ford

“We first reduce the price to a point where we believe more sales will result. Then we go ahead and try to make the price. We do not bother about the costs. The new price forces the costs down. The more usual way is to take the costs and then determine the price, and although that method may be scientific in the narrow sense, it is not scientific in the broad sense, because what earthly use is it to know the cost if it tells you you cannot manufacture at a price at which the article can be sold?”

“The low price makes everybody dig for profits. We make more discoveries concerning manufacturing and selling under this forced method than by any method of leisurely investigation.

“Suppose we had borrowed, what would have happened? Should we have been better fitted to go on with our business? Or worse fitted? If we had borrowed we should not have been under the necessity of finding methods to cheapen production. Had we been able to obtain the money at 6 per cent. flat, the interest charge alone on a yearly production of 500,000 cars would have amounted to about four dollars a car.”

“The principles of assembly are these: (1) Place the tools and the men in the sequence of the operation so that each component part shall travel the least possible distance while in the process of finishing. (2) Use work slides or some other form of carrier so that when a workman completes his operation, he drops the part always in the same place—which place must always be the most convenient place to his hand—and if possible have gravity carry the part to the next workman for his operation.”— Henry Ford

“We announced and put into operation in January, 1914, a kind of profit-sharing plan in which the minimum wage for any class of work and under certain conditions was five dollars a day. At the same time we reduced the working day to eight hours—it had been nine—and the week to forty-eight hours. This was entirely a voluntary act. There is nothing to such standards and customs. They have to be wiped out. Otherwise, we cannot abolish poverty.”

“In 1914, when the first plan went into effect, we had 14,000 employees and it had been necessary to hire at the rate of about 53,000 a year in order to keep a constant force of 14,000. In 1915 we had to hire only 6,508 men and the majority of these new men were taken on because of the growth of the business. With the old turnover of labour and our present force we should have to hire at the rate of nearly 200,000 men a year—which would be pretty nearly an impossible proposition.”

“The ordinary railway organization is rigid; a message has to go up through a certain line of authority and no man is expected to do anything without explicit orders from his superior. One morning I went out to the road very early and found a wrecking train with steam up, a crew aboard and all ready to start. It had been 'awaiting orders' for half an hour. We went down and cleared the wreck before the orders came through; that was before the idea of personal responsibility had soaked in.”

“In 1905 I was at a motor race at Palm Beach. There was a big smash-up and a French car was wrecked. I picked up a little valve strip stem. It was very light and very strong. I asked what it was made of. Nobody knew. I gave the stem to my assistant. Find out all about this, I told him. That is the kind of material we ought to have in our cars. He found eventually that it was a French steel and that there was vanadium in it. We tried every steel maker in America—not one could make vanadium steel.”— Henry Ford

“The time for a business man to borrow money, if ever, is when he does not need it. That is, when he does not need it as a substitute for the things he ought himself to do. If a man's business is in excellent condition and in need of expansion, it is comparatively safe to borrow. But if a business is in need of money through mismanagement, then the thing to do is to get into the business and correct the trouble from the inside, not poultice it with loans from the outside.”

“An industrial concern which is wide enough awake to reorganize for efficiency, and honest enough with the public to charge it necessary costs and no more, is usually such an enterprising concern that it has plenty of jobs at which to employ the tenth man. It is bound to grow, and growth means jobs. The tenth man was an unnecessary cost. The ultimate consumer was paying him. But the fact that he was unnecessary on that particular job does not mean that he is unnecessary in the work of the world.”

Assembly Line Design Principles
Three Core Principles for Efficient Production Flow
Ford's assembly line method reduced production time from 20 minutes to 5 minutes per unit by applying three core principles: sequential tool and worker placement to minimize part travel distance, gravity-assisted work slides for automatic part transfer, and sliding assembly lines for convenient part delivery. The framework emphasizes iterative refinement through experimentation with line height, speed, and task subdivision.
Components
- Sequence Tool and Worker Placement
- Use Gravity and Work Slides
- Implement Sliding Assembly Lines
- Subdivide and Test Iteratively
- Eliminate Worker Movement
Prerequisites
- Repeatable product design
- Sufficient production volume to justify fixed tooling
- Willingness to experiment with layout
Success Indicators
- Reduction in production time per unit
- Decrease in worker steps per shift
- Improved quality consistency
Failure Modes
- Line speed too fast causes errors
- Insufficient task subdivision leaves bottlenecks
- Worker resistance to specialization

Customer Lifetime Value
EconomicsThe sale of a product is not the end of the relationship but the beginning. A dissatisfied customer is the worst form of advertising, while a satisfied customer creates compounding returns through repeat purchases and word-of-mouth. The lifetime value of a customer far exceeds the profit on a single transaction, making post-sale service economically critical.

Chicago meatpacking overhead trolley system
Ford explicitly states that the assembly line idea came in a general way from the overhead trolley that Chicago meatpackers used in dressing beef. The packers had developed a continuous-flow disassembly system where animal carcasses moved past stationary workers, each performing one specialized cut. Ford inverted this concept: instead of disassembling a complex product (beef) by moving it past workers, he assembled a complex product (automobile) by moving it past workers. The key insight was that the WORK moves to the WORKER, not vice versa, eliminating the largest time sink in production—workers walking between stations.
Ford describing the origin of the assembly line method in Chapter V
Russian Soviet production failures under committee management
Ford uses the Soviet experiment as a cautionary tale about the dangers of separating authority from expertise. When Russian factories were run by committees after the revolution, production collapsed. The committees spent more time debating than producing. When skilled managers, engineers, and foremen were expelled as class enemies, thousands of tons of materials were spoiled. The Soviets eventually had to offer large sums to lure the expelled experts back. Ford draws a parallel to business: when decision-making authority is distributed across many people (committees, multiple approval layers), the work suffers. Real work requires concentrated authority and accountability, not consensus.
Ford discussing the failures of Soviet industrial management in the Introduction
Axe handle craftsman versus machine production
Ford contrasts an old craftsman making axe handles by hand in a dark shop (8 handles per week at $1.50 each, each unique and some unbalanced) with modern machine production (better handles at a fraction of the cost, all identical and perfectly balanced). The story illustrates how machinery applied intelligently does not destroy craft—it democratizes quality. The hand-made handles were expensive, inconsistent, and took enormous labor. Machine-made handles are superior in every way and affordable to all. The same logic applied to automobiles: hand-built cars were playthings for the rich; machine-built Fords put transportation within reach of the working man.
Ford explaining why mechanization benefits rather than harms workers in Chapter IV
One-horse shay design philosophy
Ford references the 'one-horse shay' (from Oliver Wendell Holmes's poem 'The Deacon's Masterpiece') as his ideal for automotive design. In the poem, a deacon builds a shay so perfectly balanced that every part is of equal strength—when it finally fails after 100 years, every part fails simultaneously. Ford adopts this as a design principle: build every component to the exact strength required for its purpose, no more and no less. Overbuilding one part wastes material and adds weight; underbuilding creates a failure point. The goal is perfect balance where the whole system is optimized, not individual components over-engineered.
Ford explaining his design philosophy in Chapter IV
Transportation system metaphor for money
Ford describes money as part of the transportation system, a method of conveying goods from person to person, just as railways and roads transport physical objects. This engineering metaphor clarifies money's functional role: it should enable exchange, not obstruct it. Just as a road should stay passable and a railway should stay on schedule, money should maintain constant value. The analogy makes abstract monetary policy concrete: inflation is like a road that changes width unpredictably, or a railway gauge that shifts from day to day.
Ford explaining his monetary philosophy in the context of the 1921 crisis
Hospital diagnosis protocol borrowed from factory quality control
The Ford Hospital's independent multi-diagnosis system directly parallels manufacturing quality control: multiple independent inspectors checking a part before it advances, with no communication between inspectors to prevent groupthink. In a factory, one inspector might miss a flaw another catches; in medicine, one doctor might miss a diagnosis another sees. The principle is identical: independent parallel evaluation catches errors that serial evaluation misses. Professional etiquette in medicine (like not contradicting another doctor's diagnosis) is analogous to an inspector deferring to a senior inspector's judgment rather than reporting what they actually see.
Description of Ford Hospital admission process
Railroad awaiting orders like factory bottleneck
A wrecking crew with steam up, sitting idle awaiting orders, is identical to a production line stopped because a part hasn't been released by the planning department. In both cases, the capability exists, the need exists, but a procedural bottleneck prevents action. Ford's solution (personal responsibility, not hierarchy) applies to both: let the person with the capability and the visibility of the need make the decision. The wreck cleared before the orders arrived is like a factory foreman who starts a production run without waiting for formal approval because the customer needs it and the materials are ready.
Railroad turnaround example
Borrowing money like taking another drink
Ford compares borrowing to cover operational problems to an alcoholic taking another drink to cure a hangover. The drink (debt) provides temporary relief but makes the underlying problem worse. The cycle reinforces itself: the next crisis requires more borrowing, just as the next hangover requires more alcohol. The only cure is to stop drinking (borrowing) and address the root cause (operational inefficiency or alcoholism). This parallel captures both the false relief of symptomatic treatment and the progressive worsening that comes from not addressing root causes.
