The Universe of Design: Horst Rittel's Theories of Design and Planning

This book examines the theoretical foundations of the processes of planning and design.

When people – alone or in groups – want to solve problems or improve their situation, they make plans. Horst Rittel studied this process of making plans and he developed theories – including his notion of "wicked problems" – that are used in many fields today. From product design, architecture and planning – where Rittel’s work was originally developed – to governmental agencies, business schools and software design, Rittel’s ideas are being used. This book collects previously unavailable work of Rittel’s within the framework of a discussion of Rittel’s theories and philosophical influences.

Jean-Pierre Protzen is Professor of the Graduate School at the University of California, Berkeley. He was Horst Rittel’s colleague and collaborator for over twenty years and since Rittel’s death in 1990 has continued teaching Rittel’s work at Berkeley.

David J. Harris was Protzen’s student at Berkeley, and his dissertation, "Design Theory: From Scientific Method to Humanist Practice," relied heavily on Rittel’s work. He currently works as an editor and writing coach.
