Next-Generation Human Systems Integration Framework and Toolset Prototype

Solicitation # bf1e6a1f-27f8-4540-afec-9134c5890c5e

The Department of Defense is seeking industry, academic, and commercial partners to develop a Next-Generation Human Systems Integration Framework and Toolset Prototype. This initiative aims to replace outdated, document-centric HSI practices with an agile, telemetry-driven approach integrated into digital engineering and DevSecOps workflows. The goal is to move away from retrospective compliance reviews toward continuous, quantitative, and predictive assessments of human-agent teaming to improve decision velocity and operator survivability across multi-domain weapons and autonomous systems. The project addresses critical gaps in current defense acquisition, specifically the lack of digital modeling for human cognitive dynamics and the risks associated with human-AI teaming, such as cognitive overload and automation complacency. The resulting modular prototype must embed real-time HSI evaluation into the digital engineering lifecycle, utilizing verification, validation, and analysis processes to achieve operational test certification. This framework will treat the human operator as a critical system component to reduce fielding timelines and minimize the need for excessive operator training.
