The increasing complexity of military command and control systems (C2-systems) requires a robust framework for integrating emerging technologies effectively. This article is part of a research project employing Design Science Research Methodology (DSRM) with the primary objective of developing a conceptual framework, including models and methods, designed to assist designers and military commanders in assessing and understanding C2-systems from a socio-technical perspective. Additionally, the research aims to provide guidance on analyzing how individual sub-systems in a C2-system influence the entire system. In previous publications, the authors have explored the challenges associated with the integration of emerging technologies into C2-systems, and have also outlined an initial iteration of a concepts model and a goal model. This article addresses the refinement and stakeholder validation of these models, and outlines an in-depth exploration of the decomposition process from high-level goals to specific sub-goals and requirements. Following the DSRM, the authors have engaged stakeholders from the military, research and acquisition domains in a series of workshops. These were designed to extract feedback and insights, ensuring that the models are both accurate and relevant. Data elicited during these sessions were analyzed to validate the coherence of the overall structure as well as the semantic quality of proposed models. The findings indicate that combining goal models with a concepts model, enhances the understanding of, and the requirements on, C2-systems. Moreover, the validation through stakeholder engagement not only refines the goal and concepts model but also fosters a shared understanding among stakeholders regarding the objectives and challenges associated with integration of emerging technologies. The results presented in this article provide actionable insights for practitioners seeking to understand and improve military C2-systems. The results also highlight the importance of both conceptual and goal-oriented frameworks in guiding the understanding and integration of emerging technologies, ultimately contributing to more effective C2-systems.
