In this SEI Podcast, Nickolas Guertin, a senior systems engineer with the SEI's Software Solutions Division, and Douglas Schmidt, associate provost of research at Vanderbilt University and former chief technical officer at the SEI, discuss strategies for creating architectures for large-scale, complex systems that comprise functions with a wide range of requirements. This is one of the most challenging areas in U.S. Department of Defense acquisition, and this approach and the strategies discussed are important to the future of our large systems.
