خلاصه	Descriptive Phenomenology, systematised by Amedeo Giorgi at Duquesne University, is a rigorous qualitative method for uncovering the general psychological structure of a lived experience. Drawing directly on Husserl's transcendental phenomenology, Giorgi's four-step procedure — epoché, whole reading, meaning-unit discrimination, and transformation into disciplinary language — produces a stable, replicable description of what makes an experience essentially what it is, without theoretical interpretation or causal explanation.	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.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.	Narrative analysis is a qualitative research method, synthesised canonically by Catherine Kohler Riessman (2008), that examines how individuals storise their lived experiences and construct meaning through the telling. Drawing on life history, biographical, and narrative inquiry traditions, it treats the story itself — not just its content — as the unit of analysis, attending to temporal sequence, plot structure, and the social context in which a narrative is produced.
