Practical Framework
Diagnostic Toolkit
Most systems that resist change are not broken in the way their managers, designers, or reformers think they are. This toolkit applies five questions from cybernetics to diagnose why a system is failing and what kind of intervention would actually address the root cause.
The questions are domain-agnostic. The same diagnostic logic applies whether you are looking at a hospital, a government department, a school, a company, or a social movement.
How to use this
Facing a failing system
Start with Question 1 and work through the sequence. Each question builds on the last. By Question 3 you will usually have identified the root cause.
Recognising a specific symptom
"Things keep getting worse" → Q1 or Q4. "Can't get on top of complexity" → Q2. "No strategic adaptation" → Q3. "Nothing works independently" → Q5.
Designing a new system
Use the questions in reverse. Start with Q5 (what boundaries must be preserved?), work back to Q1 (what should this system actually be controlling?).
Five Questions
What is actually being controlled here?
Identify the gap between stated goals and operational goals: what the system's behaviour is actually organised to maintain.
Perceptual Control Theory
Where is the variety mismatch?
Determine whether the controller has sufficient complexity to govern the system it is responsible for.
Ashby's Law of Requisite Variety
Which function is missing?
Locate the specific architectural component (coordination, intelligence, identity) that is absent or broken.
The Viable System Model
What is the feedback structure?
Map the circular causality: which loops are amplifying the problem rather than correcting it.
Feedback and homeostasis
What is the viable scope?
Assess whether the system's boundaries are intact enough for self-organisation, and where overconnectivity is destroying them.
The Free Energy Principle
Theoretical roots
Each question is grounded in a distinct body of cybernetic theory developed between 1948 and the present. The framework draws on Perceptual Control Theory (Powers), the Law of Requisite Variety (Ashby), the Viable System Model (Beer), feedback and homeostasis (Wiener, Cannon, Ashby), and the Free Energy Principle (Friston).
