The Logic of Change

Making Better Decisions from First Principles

The book introduces a disciplined way to examine what changed before jumping to conclusions about what the change means or what should happen next.

The starting problem

Understand the change before responding to its consequences.

When something important shifts, attention naturally goes to the most visible problem. The Logic of Change begins earlier: what changed, what drove it, how did it move, and what else did it affect?

The core structure

Two stages. One discipline.

1

Universal Change Framework

Build a purpose-free map of the change itself.

2

Purpose-Centric Impact Framework

Apply the completed map to a declared purpose.

Change information first. Purpose second. Every time.
Inside the book

Six distinct purpose lenses: Prediction, Explanation, Interpretation, Mitigation, Adaptation and Innovation.

Worked analysis

Full worked runs and examples that show how the method behaves under real analytical conditions.

Who it is for

For people who make decisions while the ground is moving.
