Editorial Introduction to Issue 45 of CSIMQ: Contemporary Challenges in Digital Transformation and Complex Systems Analysis

Complex Systems Informatics and Modeling Quarterly (CSIMQ) continues to serve as a forum for high-quality research at the intersection of informatics, modeling, and the study of complex socio-technical systems. This issue brings together seven contributions that reflect the breadth and depth of current research in these fields. The issue opens with two articles that explore advanced modeling and data-driven analysis within complex economic and organizational environments. The next two articles shift the focus toward the digital transformation of public services and the organizational capabilities needed to manage such change. The rest three articles address organizational transformation, IS integration challenges, and regulatory compliance in increasingly complex digital ecosystems. Together, the articles in this issue reflect the journal’s commitment to advancing knowledge on the modelling, governance, and transformation of complex systems. They showcase how researchers combine conceptual rigor, empirical investigation, and methodological innovation to address contemporary challenges in digital transformation, public-sector innovation, organizational alignment, and cybersecurity governance.
