He is best known for popularizing the concept of wicked problem, but his influence on design theory and practice was much wider. His field of work is the science of design, or, as it also known, the area of design theories and methods (DTM), with the understanding that activities like planning, engineering, and policy making are included as particular forms of design."@en . . . . . .

His field of work is the science of design, or, as it also known, the area of design theories and methods (DTM), with the understanding that activities like planning, engineering, and policy making are included as particular forms of design. In response to the perceived failures of early attempts at systematic design, he introduced the concept of \"second generation design methods\" and a planning/design method known as issue-based information system (IBIS) for handling wicked problems."@en . . . . .
