Tóm tắt	Comparative multiple case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify patterns, contrasts, and transferable findings. Rooted in Robert Yin's case study methodology and Robert Stake's multiple-case analysis framework, it combines the rich contextual insight of single-case work with the analytical leverage gained by examining how phenomena unfold similarly or differently across distinct settings.	A single-case study is a qualitative research design that investigates one bounded instance — an organization, program, event, individual, or community — in its real-world context through multiple converging sources of evidence. Developed into a rigorous social-science method chiefly by Robert Yin and Robert Stake, it is especially powerful when the case is unique, extreme, critical, or revelatory, and when the research question begins with 'how' or 'why' rather than 'how many.'
