SystemsThinking

Use the Iceberg workflow to descend from the visible event through recurring patterns to the structure and mental models generating them. Then build a causal loop diagram to confirm the feedback loops driving the behavior before choosing an intervention.

A causal loop diagram connects 5-15 variables with arrows labeled by polarity, where plus means same-direction change and minus means opposite. Loops with an even count of negative arrows are reinforcing and amplify change; odd counts are balancing and seek a goal.

The ten canonical archetypes include Fixes That Fail, Shifting the Burden, Limits to Growth, Tragedy of the Commons, and Drifting Goals. Each has a documented loop structure and canonical intervention, so matching the pattern unlocks a known fix.

Skip it for genuinely complicated problems with knowable cause-effect chains, acute crises requiring immediate firefighting, and simple domains where best practices already exist. It also fails when stakeholders cannot agree on system boundaries.

Meadows' 12 leverage points rank intervention targets from weakest (parameters, buffers) to strongest (system goals, paradigms, transcending paradigms). Effective leverage combines the level's strength with feasibility, so bundle a tactical low-level fix with a structural high-level change.
