INTRODUCTION

English translation pending.

CORE DEFINITION

A rule of thumb in problem solving, often cited in engineering and management practice, holding that the act of stating a problem precisely accomplishes much of the work of solving it. Writing forces the vague to become specific by fixing boundaries, constraints, and goals. The core claim is that clarity of statement is itself progress. The qualification is that the rule applies to problems that can be articulated, not to those whose difficulty lies in execution rather than in definition.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Written Statement: Stop and write the problem in plain sentences before attempting a solution. - Use Boundary Setting: Specify the constraints, the goal, and what is out of scope. - Use Solution Scan: Read your own definition back and check whether the answer is already implied.

Anchor fast decisions

Vague difficulty feels unmanageable because it has no edges, so effort is spent reacting to a diffuse discomfort instead of addressing a defined target. Writing forces the separation of what is known from what is assumed and fixes the constraints in place. Once the statement is precise, the space of possible solutions narrows sharply, and the answer is often already visible in the definition.
