Causal Loop Diagram

Turns relationships, patterns, and leverage points into a tangible result by collecting variables, drawing causal links, and discussing leverage points.

Core question
Which feedback loops create the observed behavior, and which leverage point inside the system shifts it sustainably?

Purpose

The method helps clarify relationships, patterns, and leverage points concretely. It maps relationships, patterns, and feedback loops. The outcome is captured as a causal loop diagram, feedback notes, and leverage points.

How it works

The team follows the steps: collect variables, draw causal relationships, label polarity, identify feedback loops, and discuss leverage points. Each step is captured visibly. At the end, a causal loop diagram, feedback notes, and leverage points are available so decisions, tests, or actions can follow directly.

Deep dive

In detail

Causal Loop Diagram follows a clear working logic: collect variables, draw causal relationships, label polarity, identify feedback loops, and discuss leverage points. This turns the method into a visible thinking process rather than only a conversation. Participants move step by step from raw material, observations, or options toward a shared structure. The result is a causal loop diagram, feedback notes, and leverage points that support decisions, learning, or further planning.

Facilitation

Prepare a clear guiding question, the right information, and a visible workspace. Plan about 1-3 h with 2-8 people and use the format in a facilitated workshop. The method needs clear structure and preparation; short timeboxes, visible intermediate results, and a parking lot for open questions help.
