INTRODUCTION

English translation pending.

CORE DEFINITION

The gear effect describes how meshed gears transmit motion through a fixed ratio: a small gear driving a large one multiplies torque while reducing speed, and a large gear driving a small one multiplies speed while reducing torque. The same trade-off appears in organizations, where small units move quickly with little force and large units exert force but change direction slowly. The mechanical analogy is used to explain why large firms and small firms cooperate. Key qualification: the ratio is fixed by design, so the trade-off cannot be escaped without changing the gearing.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Identify the ratio: work out how much input produces how much output in the system. - Choose the trade: decide whether you need force or speed before setting the gearing. - Design the mesh: pair a fast unit with a strong one so each supplies what the other lacks.

Anchor fast decisions

A fixed gear ratio conserves the product of force and speed, so increasing one necessarily reduces the other. In organizations the same conservation applies: processes that concentrate decision rights gain the ability to commit large resources but lose the ability to change direction quickly. The constraint is structural, so it cannot be resolved by effort alone.

First Principles

In philosophy and science, a first principle (or first principles) refers to a basic proposition that cannot be deduced from any other proposition or assumption. The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.
