Information systems business value (ISBV) has been a key research topic for the IS research community. While the vast majority of ISBV research demonstrates the positive relationship between IS and firm performance, the fundamental question of the causal relationships between IS and business value remains partly unexplained. Moreover, researchers do not share a unified understanding of ISBV concepts. Therefore, this research intends to synthesize the past 30 years of empirical ISBV research, identify the gaps and shortcomings, conceptualize the ISBV concepts, and propose possibilities for further research that will widen the current narrowly-shared ISBV bottom line. The authors aim to synthesize (1) different operationalization of concepts in existing ISBV research; (2) IS determinants, consequences, and the relations among the variables; (3) the role of contextual factors; and (4) the adopted theoretical views.
