Resum	Multi-source participant observation is a qualitative data collection technique in which the researcher is embedded within a social setting and systematically gathers observational data from multiple vantage points, sites, or informant roles simultaneously. By triangulating across sources, the method strengthens credibility and provides a richer, more complete picture of social phenomena than single-site observation alone.	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.	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.
