摘要	Focused ethnography is a condensed, problem-centred variant of classical ethnography in which a researcher with prior domain knowledge enters a specific social setting for a bounded period — typically days to weeks rather than months or years — to study one clearly defined issue or practice. Developed as a response to the time and resource constraints of applied research, it is widely used in healthcare, organisational studies, and professional education, where the researcher's existing familiarity with the setting allows rapid, targeted data collection without sacrificing ethnographic depth.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.	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.
