What are System Archetypes?
Let’s go step by step so you get a clear foundation in System Archetypes.
🔹 1. What Are System Archetypes?
System archetypes are recurring patterns of behavior that show up in complex systems across different domains (business, transport, health, environment, logistics, etc.).
- They were first introduced by Peter Senge in The Fifth Discipline (1990).
- Archetypes are made up of causal loop diagrams (CLDs) — maps showing feedback loops (reinforcing and balancing).
- They help us see underlying structures, not just surface symptoms.
👉 Think of them as “templates of common systemic problems.”
🔹 2. Why Are They Useful?
- They reveal why well-intentioned solutions often fail.
- They guide us to identify leverage points (where small changes can lead to big, sustainable improvements).
- They are transferable: the same archetype might explain congestion at a port, delays in healthcare, or supply shortages in retail.
🔹 3. Key Building Blocks
- Feedback loops:
- Reinforcing loop (R): amplifies change (growth or decline).
- Balancing loop (B): seeks stability, counteracts change.
- Delays: gaps between action and visible effect — often cause unintended consequences.
🔹 4. Common System Archetypes
Here are some of the most frequently used (with a short explanation):
- Fixes that Fail
- A quick fix solves a problem short-term but creates unintended side effects that worsen the issue later.
- Example: Expanding port capacity eases congestion → but attracts more ships → congestion returns.
- Shifting the Burden
- Reliance on short-term solutions reduces motivation to tackle root causes.
- Example: Rerouting ships to nearby terminals instead of fixing inefficient port operations.
- Limits to Growth
- Growth continues until it hits a limiting factor (capacity, resources, regulation).
- Example: A port expands throughput → but hinterland road/rail capacity becomes the bottleneck.
- Tragedy of the Commons
- Shared resources get overused because each actor acts in self-interest.
- Example: Too many carriers schedule arrivals in the same time slots → congestion.
- Success to the Successful
- Two entities compete; early advantage reinforces itself, while the other falls behind.
- Example: One port invests early in automation → attracts more traffic → generates more revenue → invests more.
🔹 5. A Simple Visual (Fixes that Fail)
Problem → Apply Quick Fix → Temporary Relief
↓
Unintended Consequences (Delay)
↓
Problem Worsens
This circular causality explains why congestion, delays, or inefficiencies often come back stronger.
🔹 6. How to Use Archetypes
- Identify repeating problems → e.g., port congestion reappears every year.
- Map feedback loops with a causal loop diagram.
- Diagnose the archetype that best fits (Fixes that Fail, Shifting the Burden, etc.).
- Identify leverage points → usually deeper structural changes rather than symptomatic fixes.
- Test interventions (using system dynamics modeling if possible).
✅ Key insight: Archetypes shift thinking from “How do we fix this problem now?” to “What structure causes this pattern, and how can we redesign it?”
