further emphasize that no strategy is inherently superior or inferior to the other. Consequently, what is most important is not the label that is attached to a particular strategy, but whether it will enable the authors to answer theparticular research question(s) and meet the objectives. Yin (2003) further suggests that there are three criteria used in the selection of research strategy these include:
i. Form of research question ii. The extent of control an investigator has over behavioral events
iii. The degree of focus placed on contemporary events.In addition, when case strategy has been chosen the researcher can choose between single case study and multiple case studies. Yin (2003) also points out that a single case study is employed when the researcher aims to test one case against theory allowing for deep research, in order to test numerous variables. On the other hand a multiple case study is when the researcher compares and contrasts cases increasing validity and allowing for comparison and generali zation.
