Real-time Delphi
Real-time Delphi (RTD) is an advanced form of the Delphi method. The advanced method “is a consultative process that uses computer technology” 〔Hartman, F. T., & Baldwin, A. (1995). Using Technology to Improve Delphi Method.
Journal of Computing in Civil Engineering, 9(4), 244-249.〕 to increase efficiency of the Delphi process.
==Definition and idea==
Gordon and Pease 〔Gordon, T. J., & Pease, A. (2006). RT Delphi: An Efficient, “Round-less”, Almost Real Time Delphi Method. Journal of Technological Forecasting and Social Change,73(4), 321-333.〕 define the advanced approach as an innovative way to conduct Delphi studies that do not involve sequential “rounds” and consequently lead to a higher degree of efficiency with regard to the time frame needed to perform such studies. Friedewald, von Oertzen, and Cuhls 〔Friedewald, M., von Oertzen, J., & Cuhls, K. (2007). European Perspectives on the Information Society (EPIS) (Delphi Report Deliverable 2.3.1). European Techno-Economic Policy Support Network (ETEPS Net).〕 underline that aspect by writing, in “a Real-Time-Delphi, the participants do not only judge twice but can change their opinion as often as they like when they see the aggregated results of the other participants”. So, here it becomes clear that the Real-Time Delphi approach requires real-time calculation and provision of group responses. Friedewald et al.〔 further state that the Real-Time Delphi method has beneath its explorative and predictive elements also normative and communicative elements. These latter are investigated by Bolognini,〔. The author argues that computer-based Delphi can be especially relevant in the context of e-democracy, not only for the roundless approach, the real-time updating of statistical response, or the large number of panellists, but for the possibility to establish split panels corresponding to different groups (such as policy-makers, experts, and citizens), which the administrator can give different tasks and privileges, depending on the issues and the type of decision-making process.〕 who explores the potential of computer-based Delphi as a communication technique for electronic democracy.
