Although Systems-of-Systems Governance (SoSG) is a promising paradigm for managing complexity in SoS environments, the field lacks prescriptive models that enable the operationalization of SoSG, being largely limited to descriptive frameworks without due scientific rigor. Objective: This thesis aims to systematize the SoSG domain by proposing a prescriptive conceptual model, culminating in the demonstration of its technical feasibility through instantiation in a real-world SoS environment, exemplified by the set of systems of a Brazilian state court, the Court of Justice of the State of Goiás (TJGO), characterized as an SoS. Method: Design Science Research (DSR) was employed. The research began with a Systematic Literature Mapping to identify gaps in the state of the art. The model was quantitatively evaluated via a Survey with experts. The practical demonstration occurred through the characterization of the model, followed by its instantiation within the TJGO SoS. Results: This work presents a Conceptual Model of SoSG evaluated by experts, with agreement on its representativeness. The instantiation of the model at TJGO confirmed its technical and operational feasibility, demonstrating that the artifact is capable of organizing the court’s technological complexity under an effective SoSG structure. Conclusion: This thesis confirmed the feasibility of the proposal, demonstrating that the model can be used to systematize the SoSG field and serve as a reference for its evolution.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/GovernançaSistemas-de-sistemasGovernança de sistemas-de-sistemas (SoSG)Modelo conceitual de SoSGSistemas de informação para tribunais de justiçaGovernanceSystems-of-systems (SoS)Systems-of-systems governance (SoSG)SoSG conceptual modelInformation systems for courtsCIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAOTese
