In this paper, we offer a case study of Callisto, an online site for sexual assault reporting, to highlight innovations in value design. We compare Callisto first to ordinary reporting systems, second to value design projects in computer/information system engineering, and third to large scale social movements and social media enterprises. Callisto stands out from other systems based on its exceptional value agency- a measure of a system’s societal reach, resource commitment, and value design engineering. As such, it provides a model for human rights and social justice campaigns.
