Soldier-Centered Design Tools: Recent Developments, Challenges, and Paths Forward

of systems in which interaction effects begin to dominate. (Such systems-of-systems concerns might include understanding the complex interactions across combat platforms and among suites of communications sensors, processors, relays, and their operators.) Similarly, our former supportability analyses must now deal with the dynamic viability of support components and their potential costs. Addressing this latter issue requires us to address organizations as systems and be able to model major functional slices of units. Recent HSI tool development work sponsored by ARL is particularly important in understanding the focus of these organizational concerns. Central to this work is ARL’s flagship task network modeling tool, IMPRINT (Improved Performance Research Integration Tool), and several complementary modeling capabilities, including C3TRACE (Command, Control, and Communications: Techniques for the Reliable Assessment of Concept Execution) and the IMPRINT Maintenance Model (IMM).
