সারসংক্ষেপ	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.
