We have been talking about the various dimensions of wicked problems, but how do we create systems that address these problems? How can we respond to the world appropriately without being determined by it? How can we do so by being fair and just? There are three levels of understanding (1)Model (2)Represent (3)Implement. Of these, the first feels the “softest” but is perhaps the most crucial step before we get into irreversible decisions.This issue is about mental models, and how a deeper understanding of various model we can use in different situations and building a vocabulary, can help us deal with the wickedness of a situation.
