Iceberg Model

Turns relationships, patterns, and leverage points into a tangible result by describing an event, identifying patterns, and selecting interventions.

Core question
Which patterns, structures, and mental models create the recurring events, and on which layer is an intervention sustainable?

Purpose

The method helps clarify relationships, patterns, and leverage points concretely. It maps relationships, patterns, and feedback loops. The outcome is captured as an iceberg worksheet, pattern notes, and intervention ideas.

How it works

The team follows the steps: describe the event, identify patterns, look for structures, make mental models visible, and choose interventions. Each step is captured visibly. At the end, an iceberg worksheet, pattern notes, and intervention ideas are available so decisions, tests, or actions can follow directly.

Deep dive

In detail

Iceberg Model follows a clear working logic: describe the event, identify patterns, look for structures, make mental models visible, and choose interventions. 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. As a result, an iceberg worksheet, pattern notes, and intervention ideas support decisions, learning, or further planning.

Facilitation

Prepare a clear guiding question, the right information, and a visible workspace. Plan about 30-60 min with 2-10 people and use the format in a workshop or asynchronously. The method stays lightweight; short timeboxes, visible intermediate results, and a parking lot for open questions are helpful.
