INTRODUCTION

English translation pending.

CORE DEFINITION

The image comes from Dong Zhongshu's memorial in the Book of Han, comparing a disordered government to a zither so far out of tune that the strings must be removed and restrung. The logic is that when the parameters themselves are wrong, whether strategy, business model, or organization, marginal repair cannot produce a different result, so the key variables must be replaced. It applies to the case of a wrong direction rather than poor execution. The qualification is the diagnostic difficulty of identifying the threshold at which repair has stopped working, since acting too early discards assets that were sound.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Diagnose the failure: decide whether the direction is wrong or only the execution is weak. - Name the parameters: identify the core variables such as model, team, and stack. - Cut and retune: abandon the sunk cost, redesign the parameters, and verify the new setup on a small scale.

Anchor fast decisions

Marginal adjustment moves a system along its existing structure, so it can improve a well-aimed effort but cannot correct a structure aimed at the wrong objective. When the parameters are wrong, every local improvement is spent serving the wrong goal, and the better the execution the further the system travels in the wrong direction. Replacing the parameters changes the structure itself, and the hard part is the threshold, since the same symptoms appear while a sound strategy is merely under-executed.
