VISUALISATION TECHNIQUES FOR A COMPLEX WORLD
In 1999, Frederic Vester published a report to the Club of Rome named “The Art of Interconnected Thinking”. The main focus of the book is about understanding complex systems, and how a number of interconnected models, what he called the Sensitivity Model, can help us do so. The Sensitivity Model is an IT-based approach, today in the ownership of Malik Management. While other IT-based approaches try to connect some 200+ variables into a database, Vester is frugal in comparison, with 10-20 variables. The advantage of his approach over the more mathematical siblings is the acceptance and use of fuzziness. We simply cannot expect to be able to get a total picture of our system with sharply differentiated concepts and mathematical variables, so stop trying to do it anyway. The consequence is: we better accept that whatever model we use, it will be incomplete and partially wrong. It would be foolish to attempt something that is 100% correct. Therefore, a more realistic ambition is to create a model which is relevant to the pragmatical perspective of the beholder, and is sufficiently apt to produce this relevance.
