By publishing this report the KBF aims to facilitate knowledge sharing among all interested parties bringing together important learnings and take-away messages on working with wicked problems. Acknowledging the existence of wicked problems means admitting to face societal challenges for which no definitive answer exists. Wicked problems are structurally complex so that it is hard to say where a given problem stops and another one begins. And stakeholders will frame these challenges in different ways so that a one-size-fits-all solution is highly unlikely. Thinking in terms of wicked problems opens up a novel repertoire of strategies to come to grips with these issues. The report guides you through three approaches, five methodologies and seven rules of thumb.
