概要	Multiple case-based institutional ethnography combines Dorothy E. Smith's institutional ethnography with a multi-site case structure, enabling researchers to trace how the same ruling relations, texts, and institutional processes operate across two or more distinct organizational or community settings. By holding the analytical framework constant while varying the site, this design reveals both the trans-local reach of ruling apparatus and the locally specific ways people navigate institutional coordination.	Multiple-case study design investigates two or more bounded real-world cases using the same research protocol, then compares findings across cases to identify patterns, contrasts, and explanatory insights that a single case could not produce. Developed primarily through Robert Yin's replication logic and Robert Stake's collective case tradition, the approach is particularly powerful when a researcher needs to determine whether a phenomenon occurs under varied conditions or to test an emerging theoretical explanation against rival contexts.
