Inter-organizational IT-governance for a system of systems

Critical Infrastructures (CI) are systems that are essential for maintaining vital societal functions, and their disruptions can have a significant negative impact on a nation's well-being. CI has become the focus of many digital advancements, resulting in them becoming increasingly intertwined. Therefore, a more holistic approach to infrastructure management must be adopted, in which CI typically organize themselves as a System of Systems (SoS). The main issue that CI organizations face is the unclarity of how to make their IT function as one system. IT-Governance (ITG) is critical to guide the implementation of SoS within individual organizations. However, current literature acknowledges the lack of research on Inter-organizational IT-Governance (IoITG), which is necessary for creating a digital SoS. This research-in-progress paper first proposes a definition for digital SoS for CI and then highlights the need for further research on IoITG capability in the context of SoS for CI.
