Fable
All the rulers were finally placed at the same counter
There were many workshops in Linhe City. Carpenters used their own rulers, blacksmiths their own scales, and dye houses their own color cards. Each claimed its products were qualified, but when they were delivered to the chamber of commerce, they often did not match.
At first the chamber of commerce met only at month's end to argue. Whose goods were returned more, whose customer complaints were fewer, whose wages were higher—everyone brought their own ledgers, and they argued until dark without reaching any conclusion.
The guild master's naive fix was to have every workshop submit thicker reports. The reports became thicker and thicker, but the problems became harder to investigate, because samples, scores, revision records, and rework reasons were scattered in different places.
After a large order failed, the chamber of commerce discovered that the same batch of goods had gone through three sets of acceptance: one for trial production, one for mass production, and one for shipment. Each set of rulers had the same name, but the standards were different.
A warehouse keeper suggested building a shared counter. All samples, test scenarios, scoring rules, manual reviews, revision comparisons, and failure cases would be registered in the same place.
From then on, every time the workshop modified a blade, switched a lacquer, or brought in a new craftsman, it all went through the same acceptance checks. Results could be compared side by side with the old version, and failures could be traced to specific causes.
The counter also kept rulers for different purposes: quick smoke checks, pre-release regression, manual review of hard cases, security red lines, and long-term monitoring. The president could finally see where quality comes from and where it goes bad.
Later, workshops from other places joined the chamber of commerce and no longer brought only verbal promises. They wanted to connect samples, scorers, versions, and results into the same process. The chamber understood that a quality loop cannot rely on scattered spreadsheets. There must be one place to manage tests, scoring, comparisons, and release thresholds, so that every change can be reviewed. Later, the shared counter also recorded responsibility for each release. Who approved it, which ruler was used as the basis, and how it was rolled back after failure could all be checked; quality thus changed from argument into a reviewable process. The workshops therefore dared to change their craft. Because each change no longer relied on the shopkeeper's memory to judge good or bad, but could be compared side by side using the same batch of scenarios, the same ruler, and old results. The chairman also dared to write the pass threshold into the delivery agreement.
