The military has limited means to objectively evaluate soldier and squad performance, leading to sub-optimal operational, training, and acquisition decisions. Part of this limitation stems from the fact that the ability to monitor, predict, and enhance soldier and squad performance is a complex System of Systems (SoS) undertaking. To address this integration challenge, we developed a comprehensive conceptual framework that maps mission-level success to measures of task effectiveness and human performance that quantify the impact of emerging technologies and interventions. In addition, by leveraging a previous effort that developed a Wearables MBSE system architecture (MBSE-SA) and methodology for military health monitoring systems, we developed a Human Performance MBSE-SA to capture and apply the conceptual framework, which provides the foundation for several system-level and program-level analyses, including gap identification. This paper presents the Human Performance MBSE-SA and an illustration of its utility in showing the connections among ongoing military research efforts, strategic source requirements, and operational use cases.
