As information technology (IT) in private and public organizations continues to gain importance, information system outsourcing (ISO) has become a critical component of corporate strategy for many institutions. Consequently, a substantial amount of research has investigated topics around ISO decisions and outcomes. However, despite decades of ISO research, analyses that focus on information system (IS) backsourcing remain scarce. Therefore, in this paper, we share the results of a systematic literature analysis of papers that consider IS backsourcing. Within our paper, IS backsourcing is integrated into the wider research landscape of ISO. Finally, our study clearly identifies the need for further and more extensive research on IS backsourcing. The high dissatisfaction and failure of outsourcing arrangements should not be ignored. Both sourcing decisions and existing outsourcing arrangements must be analysed carefully and in the long term to ensure the success of the company.
