Samenvatting	Transcendental phenomenology, founded by Edmund Husserl, is a qualitative method that seeks the universal essential structures — the invariant essences — of a consciously lived experience. By bracketing all assumptions and prior theories (epoché) and applying eidetic reduction, the researcher uncovers what an experience is in its purest, most fundamental form, independent of any particular context, culture, or individual biography. Clark Moustakas's 1994 adaptation made the method directly accessible to social-science researchers.	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.
