INTRODUCTION

English translation pending.

CORE DEFINITION

An efficiency model holding that output is decided at a small number of concrete points, so the highest-return intervention is to define a standard action or checklist at each of them rather than to work harder overall. It distinguishes the detail that determines success from the mass of detail that merely exists, and treats repeatable process rather than effort as the source of improvement. Practitioners are described as needing the perception to spot the decisive detail, the focus to handle it consistently, and the foresight to arrange present details for a future payoff. It is a production model, not a claim that everything matters equally.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Process design: Identify the two or three steps where quality is actually decided and write a checklist for each. - Focus management: Single-task the decisive step and batch the trivial ones so attention is not spread evenly. - Quality control: Inspect the points that propagate downstream instead of inspecting every output.

Anchor fast decisions

In any process a minority of steps determine most of the variance in the result, so effort spent on the rest barely moves the outcome. Fixing a standard at a decisive step removes variance once, and the improvement then repeats on every cycle without additional attention. This is why checklists outperform exhortations to be careful: they convert a one-time insight into a default that survives fatigue, handovers and scale, and the gains accumulate multiplicatively rather than additively.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Map the process and mark the two or three steps whose failure would ruin the output. 2. Write a short checklist for each marked step with observable pass criteria. 3. Batch or delegate the steps that do not affect the outcome. 4. Work on one decisive step at a time instead of switching between them. 5. Record what the checklist caught each month and revise the criteria rather than adding items.
