Developing a Human Performance Model Based Systems Engineering System Architecture (MBSE‐SA) for Defense Applications

Abstract

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.
