INTRODUCTION

English translation pending.

CORE DEFINITION

The image of carving jade and then polishing it, from the Book of Songs, applied to the pursuit of ever finer quality through iteration. As a thinking model it holds that a first version is raw material and that value is created in the cycles of adjustment that follow. The qualification is that polishing needs a stopping rule, since refinement without a defined standard of good enough consumes effort that returns nothing.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Feedback Iteration: locate the weakest part from user response and refine only that part. - Use Good-Enough Threshold: define the standard that ends polishing so effort moves to the next item.

anchor

Anchor fast decisions

A first attempt reflects the maker's assumptions, and only contact with users or materials reveals which assumptions were wrong. Each cycle corrects one assumption, so quality improves cumulatively, whereas polishing without feedback merely reinforces the original guesses.
