The document outlines a method called 'magic system mapping' which emphasizes visualizing mental models to better understand complex systems. It suggests effective group decision-making through non-verbal communication, aggregation of ideas, iterative refinement, and involving diverse perspectives. Additional resources for further information on this method are provided, including articles and TED talks.

1. Visualizing the mentalen modele
"The image of the world around us,
which we carry in our head, is just a
model. Nobody in his head
imagines all the world, government
or country. He has only selected
concepts, and relationships
between them, and uses those to
represent the real system.”
Jay Wright Forrester Pionier in Computer
Engeneering und System Thinking

2. Aggregating the different mental models
§ To aggregate the model first without verbal communication is more
effective and produces results in a similar quality
§ Non-Verbal Communication reduces biases in the group
§ Less discussions and more experimenting (adding to and playing with once
one mental model)

3. Refining and further differentiation of the systems
Iteratively add more
details to individual
parts of the system.
Work in small groups!

3 sucess factors
1. Involves as many perspectives as possible in the initial development and
further refinement of the system
2. Display the system at a public place
3. Maintain and nurture the shared understanding – for example in regular
meeting like a Backlog Refinement or with red Post Its signalizing the
changes to everybody
