Fable
The granary no longer charges by sickle, but by good wheat stored
The farm tool shop in Wheatfield Town used to charge by the sickle. How many sickles farmers bought, how many short-term laborers they hired, and whether the harvest was good or bad were all their own business. The shop only cared about selling as many as possible.
With the rainy season arriving early for several years in a row, farmers began to grow anxious. Sharper sickles and more short-term laborers meant nothing if good wheat could not get into the barn. Landowners gradually stopped asking how advanced the tools were and only asked whether qualified sacks of wheat could be delivered on time in autumn.
The farm tool shop first switched to charging by the number of short-term workers. The more people, the higher the bill. Farmers soon found this absurd: when the harvest crew filled the field ridges it looked lively, but wet wheat, rotten wheat and rework were still borne by them.
The shop then launched a deluxe sickle package, promising efficiency gains. The first season did cut faster, but drying, sorting, bagging, and inspection didn't keep up. The wheat was cut and left piled in the rain, and speed became a new form of waste.
When a major customer rejected three hundred sacks of wheat, the shopkeeper finally understood the customer's words: they do not buy sickles, headcount or busyness; they buy good wheat that can be accepted into the warehouse. As long as the result has not happened, no matter how beautiful the process is, it is hard to renew the contract.
The following year, the farm tool shop changed the contract. It charged by qualified wheat sacks entering the warehouse, and specified moisture, impurities, delivery dates and minimum volume. The shop itself decided how many sickles to use, how many day laborers to hire, which day to rush the harvest, and where to use the wheat screening cart.
The new contract made the shop more tense, but also gave it more pricing power. It had to manage weather risk, rework, labor fallback and acceptance criteria; but as long as the process became more stable, every extra bag of good wheat delivered would earn more than just the tool margin.
In the end, farmers were willing to pay a higher price because they were finally spending money on the outcome they wanted. The shop owner also understood that daring to charge by outcome required being able to control enough delivery steps. The shop owner also learned to refuse some contracts. If the customer would not define qualified grain bags, or if the shop had to bear all weather risk alone, charging by outcome would become gambling. A good contract must clearly write the acceptance criteria, exceptions, and responsibilities of both parties, so that the outcome is not just empty words. Later the shop owner's team also changed. People who could sell sickles were no longer enough; he needed people who understood weather, storage, acceptance, and fallback, because the bill was now tied to grain bags. Later, during the retrospective, everyone wrote this experience into the daily rules: first look at where on site the outcome truly changed, then decide what to keep, what to repair, and what to limit.
