They are drawn together because they share a mutual interest in a common theme: he concep- sion and planning of the artificial. Different defi nitions of design and different specifications of the methodology of design are variations of this broad theme, each a concrete exploration of what is possible in the development of its meanings and implications.
Communication is possible at such meetings because the results of research and discussion, despite wide differences in intellectual and practical perspectives, are always connected by this theme and, therefore, supplemental. Members of the scientific community, how- ever, must be puzzled by the types of prob- lems addressed by professional designers and by the patterns of reasoning they employ.
While scientists share in the new liberal art of design thinking, they are also masters of specialized sub- ject matters and their related methods, as found in physics, chemistry, biology, mathematics, the social sciences, or one of the many subfields into which these sciences have been divided. The problem of communication between scientists and designers was evident in a special conference on design theory held in New York in Reviewed in one of the initial papers,? The wicked problems approach was formu- lated by Horst Rittel in the s, when design methodology was a subject of intense interest.
Problem definition is an analytic sequence in which the designer determines all of the elements of the problem and specifies all of the requirements that a successful design solution must have. Problem solution isa synthetic sequence in which the various requirements are combined and balanced against each other, yielding a final plan to be carried into production.
In the abstract, such a model may appear at- tractive because it suggests a methodological pre- cision thatis, in its key features, independent from the perspective of the individual designer. But most important, it points toward a fundamental issue that lies be- hind practice: the relationship between determi- acy and indeterminacy in design thinking. To understand what this means, it is impor- fant to recognize that indeterminacy is quite dif- ferent from undetermined.
Indeterminacy implies that there are no definitive conditions ot limits to design problems. This is evident, for example, in the ten properties of wicked problems that Rittel initially identified in Wicked problems have no stopping rules.
Solutions to wicked problems cannot be true or false, only good or bad. In solving wicked problems there is no ex- haustive list of admissible operations.
For every wicked problem there is always more than one possible explanation, with explanations depending on the Weltan- schauung of the designer. Every wicked problem is unique.
