Tóm tắt	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.	A remote semi-structured interview is a qualitative data collection method in which a researcher conducts a guided, flexible conversation with a participant over a distance-bridging medium — telephone, video conferencing, or voice-over-IP — using a prepared topic guide with open-ended questions while allowing natural conversational elaboration. It combines the structure and comparability of a protocol-driven approach with the depth and flexibility characteristic of qualitative inquiry, delivered without physical co-presence.
