Fable
A badge for every craftsman to carry
At the craftsmen's market, every new implement had a label. At first the labels only said "sharp," "durable," "labor-saving." Buyers were tempted, but often used them wrong once they got home.
A grass-cutting knife was taken by a pharmacy to cut medicine, and the blade kept grass juice; a stone-carrying puppet was used by a small eatery to serve soup, and knocked over half the room. The craftsman argued that the tools were not broken, and that the buyer had misused them. The buyer retorted: did you ever state what it is suited for and what it is not?
The market changed its rules. The signboard had to state the origin, which scenarios had been tested, who tested it, how it performed, known weaknesses, forbidden uses and maintenance methods. If testing with a certain type of customer was insufficient, that had to be stated plainly too.
Some craftsmen disliked that the sign exposed flaws, but later found that honesty actually reduced disputes. Buyers could judge whether an item was suitable and also knew where to look if something went wrong.
One buyer saw that 'the stone-moving puppet is not suitable for narrow kitchens' and did not buy it to serve soup. The craftsman lost one sale, but avoided a compensation case. The sign set expectations straight first, and the object became easier to use in the right place.
The market chief also required that the sign be updated with testing. If a new scenario had been tried, add it; if an old shortcoming had been fixed, write clearly how it was fixed. Buyers no longer listened only to the sales pitch, but could judge whether this tool could be entrusted with their own work.
Later a new rule appeared in the market: artifacts without specification plates could not enter government procurement. Not because a plate makes an artifact better, but because buyers need to know the purpose, limitations, and responsibilities before something goes wrong. A good artifact paired with an honest plate is less likely to be taken to the wrong place. Later the craftsmen also learned to discover debts from the specification plates. Which scenarios had not been tested, which groups had not been tried, which failures had not been explained clearly—all became the next round's improvement list. The plate was shown to buyers and also forced craftsmen to be honest. Both sides had fewer misunderstandings, and subsequent improvements had a starting point.
A good specification sheet is not advertising copy; it lays out capabilities, boundaries and responsibilities. The more a tool can do, the more its users need to know where it is reliable and where it cannot be trusted.
