Σύνοψη	The Online Delphi Technique (e-Delphi) is an iterative, web-mediated consensus method in which a geographically dispersed panel of experts responds to successive rounds of structured questionnaires distributed and collected via email or a web platform. Anonymous feedback and controlled statistical summaries are fed back between rounds, guiding panellists toward convergence on priorities, predictions, or recommendations without the social pressures of face-to-face group discussion.	An online focus group is a moderated group discussion conducted via internet-based platforms — video conferencing, text chat, or asynchronous forums — to explore shared perceptions, attitudes, and experiences on a defined topic. It inherits the group-interaction dynamics of the traditional focus group while removing geographic barriers and enabling data collection from dispersed or hard-to-reach populations.
