সারসংক্ষেপ	Interpretive case study is a qualitative research design in which the researcher selects a bounded real-world case — a person, program, event, organization, or community — and seeks to understand it from the inside, through the meanings participants themselves construct. Unlike explanatory or descriptive case study, the interpretive variant foregrounds the researcher's active role in making sense of complex, context-laden data rather than testing hypotheses or cataloguing facts.	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.
