The comparison of online Delphi and real-time Delphi

In this study, we compared some fundamental characteristics of online Delphi (OL) and real-time Delphi (RT). We established a set of variables thru literature review; a platform was built to gather data with the involvement of dozens of testers. The findings of this study are including: (1) the time of use for RT is significant but the time pressure in RT survey made testers overwhelmed to manage progress of the exercise, therefore, some automatic functions are identified and suggested; (2) the RT can not only reduce time and costs needed for OL, but also can obviously increase the level of consensus in general; (3) the RT assisted in increasing convergence and consensus among testers. Furthermore, we proposed that the RT could have some potential applications which are leading to further studies.
