Session: Causal Loop Diagram

The plan translates the method into a concrete facilitated work block. Your inputs flow directly into the session brief and work artifact.

Derived automatically

Method session with 2-8. The plan uses the existing method logic and the runsheet.

Runsheet
Participation logic
Team round, shared work and alignment

Use the session for shared understanding. Contributions are collected visibly, assumptions are aligned, and open differences remain traceable in the artifact.

Outcome logic
Finish artifact

The session works directly toward Causal Loop Diagram. After the session, the artifact should be shareable, reviewable, or reusable.

  1. 1

    Phase 1: Behavior over time

    30 min

    Sketch the reference mode: show the behavior of the key variable over time as a graph (past plus expected future). Draw both observed and desired behavior. Hint: If nobody can sketch the behavior over time, data is missing. A model without a reference mode becomes theory without grounding.

  2. 2

    Phase 2: Collect variables

    30 min

    One card per variable. Variables are measurable (count, rate, share), not qualities. 'Motivation' becomes 'approval rate per survey'. About 8-15 variables. Hint: If variables are not formulated in a measurable way, the model produces unclear arrows. Minimum standard: I could theoretically quantify the variable.

  3. 3

    Phase 3: Causal arrows

    60 min

    Draw arrows between variables, each with a sign. Test: if A increases, what happens to B, all else equal? Only direct causality, no multi-step jumps. Hint: If an arrow is uncertain, mark the assumption with a question mark. Multiple steps between A and B often hide variables that need to be added.

  4. 4

    Phase 4: Identify loops

    45 min

    Find closed loops. For each loop multiply the signs: even number of minus signs = R (reinforcing), odd number = B (balancing). Note loop label and character (growth, stabilization, delay). Hint: Identify the central loops when there are several. If only reinforcing loops appear, balancing mechanisms are missing and the system would explode or collapse.

    Phase 5: Leverage points and interventions

    30 min

    Discuss leverage points per top loop (Donella Meadows: parameters, loop strengths, loop structure, goals, paradigms). Sketch one concrete intervention per leverage point. Hint: Parameter changes are the lowest leverage level. If all interventions are parameters, the facilitator asks for structure- or goal-related leverage points.

Session Brief: Causal Loop Diagram

Goal

Artifact: Causal Loop Diagram

Working Question

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

Context

Data points or reports that show the suspected behavior over time; relevant hypotheses about causes; existing quick fixes and their (failed) success.

Setup

  • Format: Method session
  • Duration: 2-4 h
  • Mode: Workshop
  • Participants: One facilitator with a systems-thinking background; 3-6 participants with different system knowledge; one model writer who sets arrows consistently; optional domain expert.
  • Owner: One facilitator with a systems-thinking background
  • Participation mode: Team round, shared work and alignment
  • Outcome logic: Finish artifact

Participation Logic

Use the session for shared understanding. Contributions are collected visibly, assumptions are aligned, and open differences remain traceable in the artifact.

Outcome Logic

The session works directly toward Causal Loop Diagram. After the session, the artifact should be shareable, reviewable, or reusable.

Input

Whiteboard or Miro board; arrows with polarity (+/-) and loop labels (R for reinforcing, B for balancing); notation cheat sheet visible; prepared variable list.

Preparation

Notation legend visible: arrow with + means same direction (more A -> more B), arrow with - means opposite direction. R loops reinforce, B loops balance. Rule: every variable is a measurable quantity, not an adjective.

Agenda

  1. Phase 1: Behavior over time (30 min) Owner: Facilitator Action: Sketch the reference mode: show the behavior of the key variable over time as a graph (past plus expected future). Draw both observed and desired behavior. Hint: If nobody can sketch the behavior over time, data is missing. A model without a reference mode becomes theory without grounding. Output: Causal Loop Diagram

  2. Phase 2: Collect variables (30 min) Owner: Facilitator Action: One card per variable. Variables are measurable (count, rate, share), not qualities. 'Motivation' becomes 'approval rate per survey'. About 8-15 variables. Hint: If variables are not formulated in a measurable way, the model produces unclear arrows. Minimum standard: I could theoretically quantify the variable. Output: Feedback Notes

  3. Phase 3: Causal arrows (60 min) Owner: Facilitator Action: Draw arrows between variables, each with a sign. Test: if A increases, what happens to B, all else equal? Only direct causality, no multi-step jumps. Hint: If an arrow is uncertain, mark the assumption with a question mark. Multiple steps between A and B often hide variables that need to be added. Output: Leverage Points

  4. Phase 4: Identify loops (45 min) Owner: Facilitator Action: Find closed loops. For each loop multiply the signs: even number of minus signs = R (reinforcing), odd number = B (balancing). Note loop label and character (growth, stabilization, delay). Hint: Identify the central loops when there are several. If only reinforcing loops appear, balancing mechanisms are missing and the system would explode or collapse. Output: Causal Loop Diagram

  5. Phase 5: Leverage points and interventions (30 min) Owner: Owner Action: Discuss leverage points per top loop (Donella Meadows: parameters, loop strengths, loop structure, goals, paradigms). Sketch one concrete intervention per leverage point. Hint: Parameter changes are the lowest leverage level. If all interventions are parameters, the facilitator asks for structure- or goal-related leverage points. Output: Feedback Notes

  6. Publish artifact (10 min) Owner: Owner Action: Check the artifact for completeness, define location, set version or status, and name review recipients. Output: Causal Loop Diagram

Ready to use when
  • Working question, owner, and target artifact are visible.
  • The result fits Causal Loop Diagram.
  • One version per iteration with date. Document model changes with justification. Mark hypothesis arrows separately from validated arrows so model quality stays visible.
  • Open questions are noted as follow-ups.
  • The next review or decision point is scheduled.
