This study proceeds from a central interest in the importance of systematically evaluating operational large-scale integrated information systems (IS) applications in organisations. The study was conducted within the IS-Impact Research Track at Queensland University of Technology (QUT). The study adopts the IS-Impact model (Gable et al., 2008) as its core theory base. Prior work within the IS-Impact track has been consciously constrained to Financial IS applications for their homogeneity. This study adopts a context-extension strategy (Berthon et al., 2002) with the aim "to further validate and extend the IS-Impact measurement model in a new context - i.e. a different IS application - Human Resources (HR)".
