Information systems research and practice have certainly realised the relevance of digital transformation. At the same time, societal challenges are pushing sustainability transformation to the top of agendas. Today, both transformations are crucial to organisations’ development. However, research and practice typically focus on one of the transformations in isolation or prioritise one over the other. An integrated perspective of the potential at both transformations’ interface is missing, which accounts for their interplay on an equal level. We call this interplay twin transformation and present a twin transformation model building on a structured literature review. The twin transformation model reflects the mutually reinforcing relationships of digital transformation and sustainability transformation on eight organisational layers. Therewith, we uncover how digital transformation enables sustainability transformation and how sustainability transformation redesigns digital transformation. Our research contributes to descriptive knowledge and forms the basis for further theorising while offering practitioners inspiration to pursue twin transformation.
