This article contributes to an ongoing research project following a Design Science Research (DSR)framework. The project focuses on the development of a conceptual framework that supports designersand military commanders with models and methods, aiming to enhance the understanding and evaluationof military Command and Control systems (C2-systems). Military C2-systems are increasingly dependenton emerging technologies, and this highlights the needs for a conceptual framework to guide integrationand development. In this article, we propose an approach to refine the goal model, specifically focusing onlow-level goals, within the context of C2-systems. The overall objective is to validate and refine existingconceptual models, particularly those relating to development aspects. We perform a structured analysis oflow-level goals to identify method components for the envisioned framework. By establishing theseconnections, the article aims to investigate the applicability of existing methods and potential method gaps.Should any disconnects emerge between low-level goals and the method components outlined in the formof a concepts model, this advocates for development of new method components. The findings contributeto practical insights regarding enhancing C2-system design and implementation strategies. The articleherby demonstrates applicability of the 4EM method in understanding and refining conceptual models.
