This paper will discuss the systematic operations of utilizing the BOXARR platform as the ‘Digital Thread’ to overcome the inherent and hidden complexities in massive-scale interdependent systems; with particular emphasis on future applications in Military Ground Vehicles (MGVs). It will discuss how BOXARR can enable significantly improved capabilities in requirements-capture, optimized risk management, enhanced collaborative relationships between engineering and project/program management teams, operational analysis, trade studies, capability analysis, adaptability, resilience, and overall architecture design; all within a unified framework of BOXARR’s customizable modeling, visualization and analysis applications.
