Their data analysis and findings demonstrate approach was adopted in this research explored how the existing capabilities at each implementation phase were effectively leveraged to propel successful. The previously successfully upgraded and implemented high level of performance fits the profile of the theory-driven case selection proposed by Akkermans and Helden (1). The scarcity of research in this area means that a qualitative research method is particularly appropriate. This method enables IS researchers to understand the relation between thoughts and practices in an organizational social context, and the embedded social meanings which can be used to explain human behavior (Gibbons, 31). Thus develops an ‘insider’s view’ (Yin, 78) of the case study organization, on which the researcher can base his/her organizational on of the phenomena under study. Most importantly, the case study approach is one of the most commonly used and well organization (Walsham,71, 72) methodological approaches in IS research (Klein & Myers, 35) as it tends more towards practicality than quantitative rigour (Murphy & Simon, 46). For this reason the qualitative methodology was deemed most relevant to this research topic.
