The embedded case study design is an empirical form of inquiry appropriate for descriptive studies, where the goal is to describe the features, context, and process of a phenomenon.
[1] A case study research methodology relies on multiple sources of evidence to add breadth and depth to data collection, to assist in bringing a richness of data together in an apex of understanding through triangulation, and to contribute to the validity of the research (Yin, 2003).
The unique strength of this approach is this ability to combine a variety of information sources including documentation, interviews, and artifacts (e.g., technology or tools).
"The case study is preferred in examining contemporary events, when the relevant behaviours cannot be manipulated" (Yin, 2003, p. 7).
The embedded case study approach is particularly relevant to examination of an environment where the boundaries between the phenomenon of interest and context are not clearly evident.
