Dialogic Design Science
Dialogic Design Science (DDS) is the theoretical foundation of the Structured Dialogic Design Process Methodology. In most publications, the methodology and/or the process is often referred to simply as Structured Democratic Dialogue, or Structured Democratic Dialogue Process.
The Institute for 21st Century AGORAS,  holds the service mark (a collective trademark) from the US Patent and Trademark Office for the commercial use of “Structured Dialogic Design” (SDD) in the field of social system design. The AGORAS do not wish to restrict scientists and practitioners across the globe from using and further developing the science and the methodology, but
certifies participation in official SDD informational events as well as achievement of levels of proficiency of practice through its certified SDD training and apprenticeship programs. The ultimate objective of this People's Science is to support people from all walks of life for practicing authentic participative democracy by applying the Co-Laboratories of Democracy approach in designing or re-designing their social systems.
The Domain of Science Model (DOSM), proposed by Professor John N. Warfield in 1987, is being employed as the contextual typology for assigning the component artifacts of the DDS in the four distinct domains of the DOSM, namely:
The theory comprises primarily of understanding the Laws of Dialogic Design Science, the roles of various actors, and certain key scientific process and phenomena including the Interpretive Structural Modeling algorithm, Erroneous Priorities Effect, Spreadthink, Situational Complexity, Theory of Change, etc.
