The rapid advancement of commercial wearable sensing technologies provides an unprecedented opportunity to gather information that improves warfighter performance during military activities and to detect the onset of illness (such as COVID‐19) through surveillance. However, the promise of improved performance and illness prevention through these technologies remains unfulfilled because of the complexity of guaranteeing that technology development outside of the standard military acquisition cycle will meet military requirements. The key to meeting this challenge is to facilitate coordination among R&D efforts, commercially developed products, and military acquisition strategies. To address this, we developed an MBSE architecture and methodology for validating independently developed wearable system designs against military end‐user needs. This methodology includes developing a conceptual framework, a model library, and a capability needs matrix that maps defense mission characteristics to physiological states and product design implementations. This architecture allows military stakeholders to determine where capability gaps or opportunities for wider application of commercial technologies exist, thus providing a bridge between externally developed wearable sensing technologies and military acquisition strategies.

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 lessons learned from 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.
