That the world is complex is a truism. How to deal with this complexity, on the other hand, is less banal. When working with experts from different fields, things become clearer: We need a common picture of the situation if we want to work together constructively and effectively.
When six people talk to each other, they have six different models of reality in their heads which the other five do not know, and that at best they can only guess at. This changes immediately when they all have a common visible point of reference: A graphic to which everyone contributes what they see and find important around a certain topic. Assured knowledge becomes visible and interrelated, dissent becomes negotiable.
This is useful, for example, in inter- and transdisciplinary R&D work, or in the risk analysis of complex infrastructure systems.
