Embedded systems pose special challenges to system evolution: they're embedded in a changing environment, often interacting with evolving processes of human organizations, and thus must be verified because of their critical nature. Complicating the situation, the analyses and testing regimens used to verify them must evolve as well. Both software engineering research and industrial practice need to improve to address these problems. While admittedly underemphasized in software engineering education, system evolution is crucial, and the challenges discussed here will be addressed by improving on the initial results presented.
