Field-Based Case Study — In-Situ Case Study Research

A field-based case study is a qualitative research design that investigates a bounded phenomenon — a case — within its real-world, natural setting through sustained on-site data collection. Combining the analytical structure of case study methodology with the direct observational immersion of fieldwork, it enables rich, context-sensitive understanding of how phenomena unfold in practice. The approach is firmly grounded in the frameworks of Robert Yin and Robert Stake and draws on anthropological traditions of participant and non-participant observation.
