Purpose
System Archetypes make recurring dynamics such as Fixes that Fail or Limits to Growth recognizable. It draws relationships, patterns, and feedback loops. The result is captured as an archetype assignment and lever list.
Systems Thinking Mapping tool
System Archetypes
Uses recurring feedback structures to explain problematic system dynamics.
Archetypes such as Fixes that Fail, Shifting the Burden, or Limits to Growth are hypotheses about loop structures. Observed behaviour must fit the archetype and use concrete variables.
Which feedback archetype explains the pattern, and where can the structure change?

System Archetypes uses match behaviour over time to causal loops of a known archetype. Assessments remain justified and context-bound.
Plot pattern
Plot pattern
Plot key variables as behaviour over time.
Select candidates
Select candidates
Compare two candidate archetypes by loop structure.
Validate loops
Validate loops

Falsify or refine the archetype with new time series and intervention effects.
A good fit when
For recurring patterns over time where linear cause lists are insufficient.
Ideal for
- Strategy diagnosis
- Change coaching
- Postmortems
Not good for
- Pure linear processes

Fictional worked example
match behaviour over time to causal loops of a known archetype as a precise working structure with a fictional example.

1. Behaviour pattern
- archetype diagnosis
- Backlog falls briefly then rises higher.
2. Archetype
- archetype diagnosis
- Shifting the Burden; alternative Fixes that Fail.
3. Loops
- archetype diagnosis
- Contractors reduce causal learning with delay.
4. Leverage
- archetype diagnosis
- Cause feedback; share of recurring tickets.
The example demonstrates the domain logic of System Archetypes; worksheets remain blank.
First step
Start with the core question: Which feedback archetype explains the pattern, and where can the structure change?
Good to do first
Deep dive
How it works
The team compares the current situation with typical archetypes and checks where similar loops become visible. The underlying patterns, side effects, and countermeasures are then worked out. This turns vague frustration into an understandable behavior pattern within the system.
In detail
System Archetypes such as Limits to Growth, Shifting the Burden, Tragedy of the Commons, or Fixes that Fail were popularized around Peter Senge and Donella Meadows. Each archetype describes a recurring structure of loops and delays with characteristic leverage points. The method helps make blind spots in initiatives visible.
Facilitation
Keep archetype cards ready. Have the team test several possible archetypes before selecting one. Discuss leverage for each archetype.
The method guide walks execution through 4 phases, timing, 4 pitfalls, and clear stop criteria.
