Ranked by what you don't already know.

A case earns attention by changing a decision, and it earns it more when nobody in the room has heard it. Obscurity therefore multiplies rather than adds: a famous case has to be extraordinarily forceful to be worth the telling.

Force

How much this case should change a decision we make. Not how interesting it is.

Consequence

The size of the footprint it left on the world.

Obscurity

6 − mean of how well known it is to the public and to innovation professionals. 5 means almost nobody.

Generality

Does the mechanism transfer beyond its own domain? A case that only teaches its own industry is worth less to a reader.

CASE-0005 · M01 Invention is not innovation · 1892–1932

Samuel Insull and the invention of the utility business model

21yield · force 5 · obscurity 4.5
What happened
Insull arrived at Chicago Edison in 1892, aged 32, after being passed over for the presidency of Edison General Electric. He concluded that the cost of electricity was governed less by fuel than by load factor — the ratio of average to peak demand — and therefore by who the customers were and how they were charged. On a visit to Brighton in 1894 he found Arthur Wright's demand meter, which recorded not only how much a customer used but how fast. Insull licensed it and introduced two-part rates in Chicago: a fixed charge for the capacity held open, and a very low charge per unit consumed. He then deliberately assembled customers whose peaks fell at different hours — streetcars in the morning, factories through the day, homes at dusk — and pursued industrial users who were self-generating. In 1898, to the National Electric Light Association, he argued that exclusive franchises should be traded for state rate regulation, at a time when most of his peers opposed it. In 1903 he committed Chicago Edison to a 5,000 kW Parsons steam turbine at Fisk Street, far larger than anything then in service, against a reluctant board.
What the popular story gets wrong
There is barely a popular story to get wrong, which is the point. Edison and Tesla are household names; the man who designed the industry's commercial and regulatory structure is not. Where Insull is remembered at all it is for the 1932 collapse of his holding-company empire and the fraud trial that followed — he was acquitted after two hours of jury deliberation — rather than for the forty years of structural design that preceded it.
What it bears on
Supports SRC-0002 (Drucker) on industry-structure change as a source of opportunity — Insull created the structure rather than responding to it. Supports SRC-0014 (Breznitz) on the stages after novelty being where value is captured: he invented almost no technology and captured an industry.
Implication for us
Almost every structural feature of the business we work in was designed by one operator between 1892 and 1912, which means those features are choices and not physics. When we treat tariff design, the obligation to serve, or the demand charge as fixed background, we are treating a hundred-year-old commercial decision as a law of nature. The two-part tariff in particular was invented to solve exactly the problem flexibility products face now.

CASE-0008 · M03 System, not gadget · 1933–1942

The Electric Home and Farm Authority: financing the demand

20yield · force 5 · obscurity 5.0
What happened
By 1935 roughly 90% of American urban homes had electricity and roughly 10% of rural ones did. Having secured the mandate to generate and distribute cheap power, TVA director David Lilienthal identified the binding constraint as neither generation nor lines but the household balance sheet: a refrigerator cost a substantial fraction of annual family income, utilities would not cut rates until demand grew, and demand could not grow until appliances were affordable. He called it a complete business stalemate. The Electric Home and Farm Authority was created by executive order in December 1933, managed initially by the TVA directors, to finance appliance purchase and home wiring — small deposit, terms up to five years, a low annual charge — while negotiating with manufacturers for cheaper models sold through local utilities and cooperatives. In 1935 it moved to the Reconstruction Finance Corporation and expanded beyond the Tennessee Valley alongside the Rural Electrification Administration.
What the popular story gets wrong
The New Deal electrification story is told as dams and transmission lines. The dams are photogenic and were not the constraint. The instrument that actually converted infrastructure into consumption was a consumer credit agency, and it is almost entirely absent from the popular account.
What it bears on
Supports SRC-0001 (Rogers) on relative advantage as something the customer must be able to realise, not merely perceive: the advantage of electricity was obvious and unreachable without the appliance. Qualifies any account of adoption that treats price per unit as the decision variable.
Implication for us
The direct modern parallel is heat pumps, home storage and EV charging, where the constraint is capital cost to the household and not generation, tariff or device performance. Any adoption forecast we produce that models unit price and not household financing is modelling the wrong variable. The historical answer was an instrument, not a campaign.

CASE-0040 · M01 Invention is not innovation · 1863 – c. 1900

The German dye industry invents the research laboratory

20yield · force 5 · obscurity 4.0
What happened
Perkin's mauveine (1856) was British and so was much of the early chemistry, but the industry was built in Germany. Bayer was founded in 1863, BASF in 1865, alongside Hoechst, Agfa and Cassella. Through the 1870s these firms did something new: they built permanent in-house research laboratories staffed with doctorate-holding chemists. Hoechst set up an analytical laboratory in 1870 and a research organisation by about 1880; BASF's laboratory took shape from 1874 under Heinrich Caro and had five or six academic chemists by 1887, with a central research laboratory designed later that decade; Bayer built the Elberfeld scientific laboratory under Carl Duisberg. The 1877 German patent law sharpened the incentive by making chemical inventions defensible. The scale of commitment is visible in BASF's synthetic indigo programme: research from 1880, commercial production in 1897, seventeen years and roughly two million pounds. By 1913 Germany was exporting on the order of 135,000 tonnes of dyes against Britain's 5,000.
What the popular story gets wrong
Two things. First, the story is usually told as chemistry — Perkin's accident, then a march of molecules — when the decisive move was organisational. Second, the origin of the industrial research laboratory is popularly assigned to Edison at Menlo Park or to Bell Labs. Historians of the field have located it in the German dyestuffs firms, and Bell Labs is downstream of a decision taken in a dye works.
What it bears on
Supports SRC-0015 (Knott): R&D is an organisational capability with measurable returns, and the returns here were captured by the firms that built the capability rather than by the country that made the discovery. Supports SRC-0022 — this is exactly the sort of finding that exists in the history-of-technology literature and is absent from the trade-book canon.
Implication for us
The lab we run is an instance of a form invented in the 1870s for a specific purpose: to convert academic training into defensible patent positions in a science-based industry. When we ask what our lab is for, the honest first answer is to check whether that original purpose still describes us, and to say so if it does not.

CASE-0030 · M07 The famous story is wrong · c. 1300 – 1494 – 1600s

Pacioli did not invent double-entry bookkeeping

18yield · force 5 · obscurity 3.5
What happened
Luca Pacioli's Summa de Arithmetica (Venice, 1494) contains the first printed description of double-entry bookkeeping — 27 pages inside a 615-page mathematics textbook. He described a method Italian merchants had already used for roughly two centuries; he did not invent it. What the Summa did was couple an existing practice to a new distribution technology: printing. Werner Sombart argued in 1916 that capitalism was unthinkable without double entry. Basil Yamey spent decades arguing the opposite from the ledgers themselves, showing merchants rarely used it to compute periodic profit at all. The dispute is unresolved and worth presenting as unresolved.
What the popular story gets wrong
Pacioli is routinely called the inventor of double-entry bookkeeping and the father of accounting. He was neither. He described, in print, a method Italian merchants had been using for roughly two centuries — de Roover traced the practice through medieval merchant account books well before 1494. Pacioli's own contemporaries were not confused about this; the attribution hardened later.
What it bears on
Qualifies SRC-0005 (Arthur): the recombination here was of a practice with a printing press, not of two technologies. Supports SRC-0012 (Godin) obliquely — the misattribution of an anonymous collective practice to a single named author is precisely the kind of tidying that conceptual history exists to undo.
Implication for us
Write down the unglamorous thing. The most consequential document in the history of business administration was a chapter inside a maths textbook, describing what practitioners already did, and it worked because it was printed. Codification of existing practice is a legitimate and undervalued form of innovation — which is, incidentally, what this repository is.

CASE-0002 · M05 Bricolage beat breakthrough · 1975–1995

Danish wind turbines against the American great leap

16yield · force 5 · obscurity 3.5
What happened
Two national wind programmes ran in parallel after the oil shocks. The United States funded large, aerodynamically ambitious machines designed largely by aerospace engineers and built to specification. Denmark's turbines came out of agricultural machinery workshops and small firms, were smaller and cruder, were sold to local co-operatives who operated them, and were revised continuously against field failures. The Danish design lineage converged on the three-bladed upwind configuration that became the world standard; the American programme produced machines that broke and a domestic industry that did not survive its own subsidies.
What the popular story gets wrong
It is usually filed as a subsidy story or a national-character story. The mechanism was neither. It was the feedback loop: distributed co-operative ownership put operators, failures and designers within one short cycle of each other, so learning accumulated in the design lineage rather than in reports.
What it bears on
Supports SRC-0003 (von Hippel) — the Danish machines were substantially user-shaped, with operators inside the design loop. Supports SRC-0018 (Edmondson) on intelligent failure: the Danish programme's failures were small, survivable and acted upon, which is the only configuration in which failure is worth anything. Qualifies any reading of SRC-0005 that treats recombination as a purely cognitive act — here it was organisational.
Implication for us
When choosing between a specified-then-built pilot and an instrumented-then-revised pilot, the second wins whenever the failure cost is survivable. Our gate criteria should therefore ask for the revision cycle time, not only the design.

CASE-0029 · M07 The famous story is wrong · c. AD 100 – 1846

The rail gauge that the Romans did not set

16yield · force 5 · obscurity 3.5
What happened
The story runs: Roman chariot ruts fixed cart axle widths, wagonways copied them, Stephenson copied the wagonways, and 4 ft 8½ in is therefore a Roman measurement. It is false, and it has been debunked since at least 1905. North-east English wagonways used no standard at all — Wylam and Blenkinsop's Middleton line ran at 5 ft, Beamish at 4 ft 4 in, Bigges Main at 5 ft 7½ in. Stephenson used 4 ft 8 in because that was Killingworth colliery's gauge where he was engine-wright, added a half inch around 1829, and the 1846 Gauge Act made it law only because eight times more track already existed at his gauge than at Brunel's 7 ft. The real convergence is duller and more interesting: Roman rutways and Northumbrian wagonways both had to fit a cart drawn by two horses in harness, roughly 1.4 m. Same constraint, no inheritance.
What the popular story gets wrong
Everything causal in it. The claim that Roman chariot ruts fixed cart widths, which fixed wagonway gauges, which fixed Stephenson's gauge, has no supporting chain. British wagonways used no common gauge: Wylam and Blenkinsop's Middleton line ran at 5 ft, a Beamish wagonway at 4 ft 4 in, Bigges Main at 5 ft 7½ in. Roman traffic was overwhelmingly pedestrian and pack, and war chariots had been militarily obsolete long before the Roman period. The Railway Magazine was already debunking the tale in 1905, which tells you how durable a good story is. The NASA solid-rocket-booster coda that usually closes the telling is a later embellishment on an already false premise.
What it bears on
Contradicts nothing in Bedrock directly, and that is its value: it is a case about how we reason. It qualifies SRC-0005 (Arthur) usefully — recombination and inheritance are real mechanisms, and this is a case where a plausible inheritance story turns out to be independent convergence on a shared physical constraint.
Implication for us
Two rules. First, path dependence is a real mechanism and therefore an attractive explanation, which makes it exactly the kind of claim to check rather than repeat. Second, when two systems share a dimension, look for a shared constraint before assuming one copied the other — the answer here is horses, not Romans.

CASE-0003 · M06 Value captured elsewhere · 1953–1971

Wichterle's hydrogel lenses and the value that left the country

16yield · force 4 · obscurity 4.0
What happened
Otto Wichterle developed hydrophilic gel polymers suitable for implantation and, after being removed from his institute post, produced the first usable soft contact lenses at home over Christmas 1961 on a spinning apparatus assembled partly from a child's Merkur construction set. The rights were subsequently sold abroad by Czechoslovak state organs on terms that returned very little to the country or to Wichterle. The global soft-lens industry was built elsewhere on the result.
What the popular story gets wrong
It is told domestically as a story of ingenuity, and it is one. The consequential part is the second half: a country can hold world-leading invention and capture almost none of the value, and the mechanism of that loss is institutional rather than technical.
What it bears on
Supports SRC-0014 (Breznitz) directly and painfully: novelty-stage invention without the stages that follow it produces prestige and no industry. Provides a domestic case for SRC-0015 (Knott) on the difference between generating knowledge and appropriating returns from it.
Implication for us
Every concept in the lab should carry an explicit appropriation question at the concept gate: if this works, who captures the margin, through what mechanism, and what would have to be true for that to be us. A concept that cannot answer it is a gift to somebody.

CASE-0001 · M03 System, not gadget · 1956–1980

Containerisation and the rebuilding of everything around a steel box

12yield · force 5 · obscurity 2.5
What happened
Malcom McLean, a trucking operator with no shipping background, ran the first container voyage in 1956. The metal box itself was trivial and not new. What took the following two decades was everything around it: purpose-built ships, gantry cranes, redesigned ports, container-compatible chassis and rail cars, the ISO dimensional standard, renegotiated dock labour agreements, and rewritten insurance and customs treatment. Cargo handling costs collapsed, and the geography of manufacturing reorganised itself around the result.
What the popular story gets wrong
It is told as an invention story with a clever outsider at the centre. The box was the cheapest component. The innovation was a two-decade renegotiation of a socio-technical system in which most of the necessary work was standards-setting, capital reallocation and labour politics — none of which appears in the telling.
What it bears on
Supports SRC-0001 (Rogers) on compatibility as an adoption constraint: containers were radically incompatible with the installed base, and the diffusion curve reflects the cost of removing that incompatibility rather than any property of the box. Also supports SRC-0005 (Arthur) on recombination — every component existed.
Implication for us
Our own candidates are mostly of this shape: a plug-in battery, a flexibility product, a metering interface. The device is the cheap part. Before a gate, state explicitly which standards, tariffs, certifications and counterparties would have to move, and treat that list — not the hardware — as the project.
