A multi-site case study investigates a defined, contemporary phenomenon that is common to two or more real-world or naturalistic settings. As well, a multi-site case study offers a means of understanding an individual, event, policy, program, or group via multiple representations of that phenomenon. In other words, by illuminating the experiences, implications, or effects of a phenomenon in more than one setting, wider understandings about a phenomenon can emerge. Typically, the research design in a multi-site case study is the same across all sites. This means the same unit(s) of analysis or phenomenon is studied in light of the same key research questions.
