Responsibility receives increasing attention in IS research and practice. IS scholars study, for example, digital responsibility, corporate digital responsibility, responsible AI or matters of digital and environmental sustainability (e.g. Green IS). These concepts often take a substantive view on responsibility. They define responsibility as ensuring digital sustainability, functionality, or data privacy and security. In his talk, Markus P. Zimmer speaks about ongoing conceptual work on taking a procedural review on studying responsibility in IS phenomena. A view that emerged from his interest in empirically studying organisations’ digital–sustainable co-transformation (or twin transformation) as one example of responsible digital transformation.
