a large number of research methodologies have been identified, Galliers (1991) for example listing fourteen, while Alavi and Carlson (1992), reported in Pervan (1994b),use a hierarchical taxonomy with three levels and eighteen categories. In Table 3.1 below, we list the methodologies identified by Galliers (1991, p.149), indicating whether they typically conform to the positivist or interpretivist paradigms. Before introducing the methodologies we use in this research, we summarise the key features of the key methodologies in the table, identifying their respective strengths and weaknesses. In the following sections, we justify our choice of methodologies and explain how they both operate and interoperate in our research.
