Zusammenfassung	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.	The Delphi technique is a structured, multi-round data collection method that harvests and refines expert opinion through iterative questionnaires and controlled feedback. Developed at RAND Corporation in the 1950s, it is designed to converge a dispersed expert panel toward a reliable consensus on complex, uncertain, or future-oriented questions — without the conformity pressures of face-to-face group discussion.
