요약	An unstructured interview is a qualitative data-collection method in which the researcher enters the conversation with a broad topic or grand-tour question rather than a fixed questionnaire, allowing the participant to direct the flow and depth of the discussion. The approach prioritises the participant's own conceptual categories and narrative logic over the researcher's pre-formed agenda, making it especially powerful for exploratory inquiry into unfamiliar or complex social phenomena.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
