সারসংক্ষেপ	Longitudinal Institutional Ethnography (longitudinal IE) combines Dorothy Smith's sociology of standpoint — institutional ethnography — with repeated data collection over time to trace how institutional texts, relations, and ruling practices shape people's everyday lives across a temporal span. By revisiting the same participants, settings, or documents at multiple time points, it reveals how institutional coordination evolves, accumulates, or intensifies over weeks, months, or years.	A longitudinal case study is a qualitative research design that combines the in-depth, contextually rich focus of case study methodology with repeated data collection across multiple time points. Rather than capturing a single snapshot, it follows one or a small number of cases — an individual, group, organisation, or programme — over months or years to trace how processes, relationships, and meanings evolve. This design is well suited to questions about how and why things change, not merely what the state of affairs is at one moment.
