Causal Loop Diagram

Map the feedback loops between the forces in your system — adoption, skill gaps, resistance, leadership attention. Mark each link as reinforcing or balancing. The loops explain why a single well-designed intervention keeps getting eaten by the system around it.

When to use Causal Loop Diagram

Use when repeated, sensible interventions produce no lasting change and nobody can say why.

What it solves

Isolated interventions are defeated by feedback loops nobody has drawn.

How to run Causal Loop Diagram, step by step

List the five to eight variables that matter. Use nouns that can go up or down (10 min).
Draw arrows for causal influence. Label each: same direction (S) or opposite (O) (20 min).
Trace closed loops. Mark each as reinforcing (compounding) or balancing (self-correcting) (15 min).
Find the loop that defeats your current intervention. That loop is where the redesign must land (15 min).

Materials needed

Whiteboard or shared canvas
Marker pens
Prior intervention history

Facilitator tips

Variables must be quantities that can rise or fall. 'Training' is not one; 'hours of coaching per team' is.
A diagram with no closed loops is a flow chart, not a causal loop diagram. Keep going.
Delays are as important as links. Mark the slow arrows.

Common pitfalls

The diagram grows to thirty variables and becomes unreadable. Cap it at eight.
Groups draw the system as it should be rather than as it behaves.

What it produces

A causal loop diagram with reinforcing and balancing loops marked, and one leverage point identified.

Origin

From system dynamics (Jay Forrester and successors). Used in the VERIFY method (letter Y) to surface why isolated interventions fail.
