خلاصه	A multiple case study (also called a multiple-case design or collective case study) is a qualitative research design in which two or more bounded cases are examined together to pursue a common research question. By studying several instances of a phenomenon in parallel, the researcher can compare patterns, identify convergences and divergences, and build more robust, transferable conclusions than a single case could support. The design draws principally from Robert Yin's case-study methodology and Robert Stake's collective case study tradition.	Phenomenology is a qualitative research approach that investigates how participants live through and make sense of a specific experience. Rooted in the philosophy of Edmund Husserl and extended by Martin Heidegger, it aims to reveal the essential structures of lived experience rather than to measure or predict outcomes. The two most widely applied variants are Husserl's transcendental phenomenology, which seeks universal essences, and Heidegger's hermeneutic phenomenology, which emphasises interpretation within context.
