Multiple Case Study

Analytic conclusion independently arising from two cases will be more powerful than those coming from a single case alone. Additionally, case study offered contrasting situations (Yin, 2003). In general, criticism about single case studies usually reflect fears about the uniqueness or artifactual condition surrounding the case (e.g special access to a key informant as a result, the criticism may turn into skepticism about the work. Therefore, the multiple case studies or in this case two case studies are more relevant to blunt such criticism and skepticism. The evidence from multiple cases is often considered more compiling and robust (Herriott & Firestone, 1983) (cited at Yin, 2003). However, according to Yin (2003), multiple case studies can require extensive resources and time beyond the means of a single student. For example, one of the case study did not fact suit the original design, under certain circumstances re-design should take place (Yin, 2003). Such re-design might involve the selection of alternative cases or changes in case study protocol (Yin, 2003). Multiple case design in this case two case studies would be the selection of two or more cases that are believed to be literal and theoretical replication (Yin, 2003). Thus the selection of the case study must be in the same contact of development.
