CSIMQ enters its second decade of existence, therefore the preface for the current issue starts with a message from the Editor-in-Chief, highlighting the journal’s mission of dealing with complexity management and systems modeling as meta-fields that have emerged from Information Science but remain relevant across diverse domains. Afterwards, the 38th issue is introduced by summarizing the four articles selected by guest issue editors on topics related to novel decision support methods or model-based frameworks for evolving or evaluating information systems. Design-oriented research is the dominant approach in these works, balancing technical design decisions insights with empirical evaluation cases. Three of the selected articles contribute with decision-support methods or frameworks – for ESG (Environment-Social-Governance) accounting, for democratized decision services and for information security management. Another article revisits UML-based model-driven software development from a new perspective.
