Yin suggests that the type of case the researcher selects hinges on the
type of information the researcher is searching for and the types of questions he/she
poses. Moreover, she explains that the degree of control the researcher wishes to have over the case as well as the emphasis on previous or present phenomena are also issues that should be considered. (Yin, 1994: 39). This study involves multiple cases study. Multiple cases are ideal as they contribute to a framework that is ideal for the collection of data. (Remenyi et al., 1998). In addition, these studies serve as
“source(s) of explanatory data” that help with the generalizations of the issues being
investigated, including “the how and why of the network explored.” In brief, the
addition and use of multiple case studies in qualitative research allows for the data to
be better explored and presented in a macro manner (Huberman and Miles, 1994:
172). The five cases that are included in this research were purposively selected. As
an inductive study, Billett (1996) indicates the value of a constructivist approach with
case studies is in developing an understanding of learning practices in the
organization.
