Fable
Not just a race to see who runs fastest
Four cities held an annual courier race. At first it only compared who ran fastest; when the finish bell rang, the fastest person was draped in a red flower. Many couriers began training only for short-track sprints, and even swapped their mail bags for empty ones.
The first year's results looked good, but problems arose during actual deliveries. Some couriers ran fast but misread the streets, some fell in the rain, and some lost their temper when an elderly person asked for directions. The city lord realized that speed alone could not tell whether a courier was reliable.
The courier guild's first fix was to add a literacy requirement. Couriers could now read the envelopes, but they could still mix urgent letters with casual ones. The second fix added etiquette, yet even the most courteous couriers still lost letters on muddy roads.
The old postmaster suggested splitting the tournament into many rounds: sunny, rainy, long routes, short routes, unfamiliar blocks, urgent letters, secret letters, misleading signs, judgment after fatigue. Each round had a different focus and also recorded its cost.
Some couriers complained that there were too many rules. The old post inspector had them look at last year's accident log: real disasters never came from slowness alone; they often came from speed, error, carelessness, fragility, and rule-breaking stacking together.
After the new tournament began, no one could reign by a single impressive result. Someone was fastest but lost points in the secret-letter arena; someone unremarkable in peacetime was steadiest on rainy nights and in complex alleys.
What the city lord finally got was not a single champion, but a complete portrait: in which scenarios this courier is usable, where it is fragile, and at what cost. Judging a complex capability requires illuminating it from many sides at once.
From then on, the tournament leaderboard no longer listed just a single ranking, but laid out each performance item clearly. Employers could pick people according to their own road conditions: urgent deliveries valued speed, secret letters valued reliability, mountain roads valued endurance. If complex capabilities are compressed into a single score, the chooser may seem to save effort, but in reality hides the risk until after the journey begins. Later, before hiring a courier, the city lord would first look at which scenarios his own needs fell into. No courier was best in every category, and a single-event champion might not suit real roads. Multi-faceted evaluation turned selection from worshipping high scores into understanding the applicable scope. This portrait was more useful than a laurel wreath, because real letter delivery was never a flat, straight track. This phrase was later written into the newcomers' handbook, reminding everyone to look at the on-site cost first before discussing effort savings. And precisely because of this reminder, when similar challenges arose later, people would not rush to apply old methods.
