Résumé	The Remote Delphi Technique applies the structured iterative consensus process of the classic Delphi method entirely through remote communication channels — email, web-based survey platforms, or dedicated collaboration tools — eliminating the need for geographic co-presence. Experts complete successive questionnaire rounds asynchronously, receiving anonymised statistical summaries of the group's prior responses before each new round, until a pre-defined consensus threshold is reached.	An online survey is a structured data collection instrument hosted on a web platform and completed by respondents via internet-connected devices. It enables large-scale, geographically dispersed data gathering at low cost and with rapid turnaround. Respondents self-administer the questionnaire at their convenience, which reduces interviewer bias and permits automatic data capture. Online surveys are the dominant mode of survey research in social, behavioural, health, and market research today.
