We are entering a time of complexity that is recognized everywhere, especially in design circles. Don Norman's latest book "Living with complexity" is a sign of this. But the fact that the world is getting more complex is not a new insight. Christopher Alexander wrote in 1964 in his book "Notes on the synthesis of form" that "more and more design problems are reaching insoluble levels of complexity" (p 3). He argues in his book that due to the increasing complexity, design can no longer be an activity that is done by people who has an innate ability to make good judgments. He argues that good intuition is not enough. Design is in need of more systematic approaches. Out of this idea grew his proposal for the use of pattern language in design. Even though Alexander argued that intuition is not enough, the notion of intuition has always and will probably continue to be a core concept when it comes to describing what is needed from a designer.
