Fable
The carpenter pinned the sketch beside the workbench
When the old carpenter took on apprentices to make new furniture, there was one iron rule: the design drawing was first drawn on paper, revised repeatedly until satisfactory, then sent to the official woodworking shop to produce the formal blueprint, and only then was material cut. A new chair went through at least seven days from idea to cutting.
Later the small shop wanted to try many display racks: today they wanted to change the shelf height, tomorrow they wanted to try curved edges, and the day after they wanted to shorten it to fit the shop corner. Every time the apprentice made a change, it had to be sent to the official workshop, and all the time was spent waiting for a stamp. The shopkeeper mistakenly thought the problem was that the apprentice drew too slowly.
He first had his apprentice draw several extra backup diagrams. As a result, the backup diagrams piled up more and more, while the dimensions that actually needed testing still changed at the last minute. The carpenter discovered that early exploration needs easy saving, comparison and retrieval of sketches, not a formal process for every idea.
So he nailed a sketch board beside the workbench. Each sketch was labeled with its purpose, dimensions, trial results, and similar styles. Apprentices could immediately pin up new ideas, and could also search old drawings by "like a narrow shop shelf" or "like a curved chair back."
In the first week, someone treated the sketch board as a finished goods warehouse and almost cut materials according to unverified drawings. The old carpenter set a rule: the sketch board serves experimentation, but before actual cutting, dimensions, materials, and load-bearing capacity must still be confirmed. Fast caching and fast changes cannot replace final acceptance.
The sketchpad let the small shop try things quickly, and also kept failures from scattering in drawers. The carpenter understood that some tools suit formal production, while others suit keeping ideas, experiments, and similar memories close at hand, helping the team explore faster.
A new apprentice later asked why they didn't just treat the sketch board as the formal drawing library. The old carpenter took out three failed sketches: one looked good but would wobble, one saved material but pinched fingers, one suited narrow shops but not damp warehouses. Sketches can help people think, but that doesn't mean they're ready for delivery.
So two paths formed beside the workbench. During exploration, the sketch board was used for quick saving and similarity search; at finalization, work moved into the formal woodworking room for load-bearing, dimension and delivery checks. The small shop thus was neither dragged down by process nor mistook immature ideas for finished products.
