ABSTRACT
This chapter highlights that ‘‘case study’’, the term itself, has multiple
meanings. It can be used to describe a unit of analysis/a choice of what is to be
studied (Stake, 2000), which aims to describe and explain the phenomenon
of interest (Zucker, 2001) or to describe a research method (Yin, 1994;
Creswell, 1998; Scapens, 1990). This chapter argues that the use of case
study as a research method, not a methodology, depends on both the nature
of the research that could be descriptive, illustrative, explorative, evaluative,
or explanative (Yin, 1994; Scapens, 1990) and the methodology (philo-
sophical assumptions) that is used by the researcher (Scapens, 1990).
