De Argumentenfabriek (The Argumentation Factory) is an independent company that helps organizations come to grips with complex problems by facilitating thinking processes (in so-called Thinking Sessions) and by visualizing information. The proprietary method we use is called De Argumentenkaart® (The Argument Map). The process of visualizing information forces people to structure their thoughts. The resulting Maps portray large amounts of information in a way that provides a clear and comprehensive overview. This allows people to make better decisions. Argument Maps are also highly suitable for recording, sharing and communicating information.

Our story

The most important activity of De Argumentenfabriek is visualization of data and information. An Argument Map for instance is a visual summary of a particular theme, usually in poster format. All relevant themes, sub-themes, arguments and facts, are logically and synoptically presented on an Argument Map. We find the content through structured sessions with expert panels and research. We then structure and visualize the content with help of our excellent graphic designers.

We also make Information Maps, Scenario Maps and other maps. For more information about our products and services, please contact Mirjam van Tiel.

De Argumentenfabriek also has a training division, called De Argumentenfabriek Denkacademie (The Argumentention Factory Thinking Academy). It offers training in clear thinking. Participants use the visual tools of De Argumentenfabriek to analyze and structure cases and examples from their own work situation. For more information about our training program, please contact Suzanne Weusten.
