Since the 1990s, business-IT alignment has been considered the appropriate organizational frame for business and IT strategies. Thereafter, with the rising importance of innovative digital technologies for performance and competitiveness, the concept of digital business strategies (DBS) emerged. The fusion of business and IT strategies is presumed to account for the inevitable transformations that digital technologies triggered. This paradigmatic shift poses new challenges to practitioners and researchers, as current assumptions regarding strategizing processes need to be questioned. This study sets out to provide a structured clarification of the current digital business strategies knowledge base. It provides a threefold contribution by: 1) structuring the research efforts on digital business strategies, 2) uncovering knowledge gaps and 3) developing an agenda for future research.
