More than other areas of processes, Information Systems have been at the core of outsourcing strategic options for years.

Nevertheless, a comprehensive review of these findings is still lacking, and a clear understanding of the overall outsourcing phenomenon is missing. Building on previous review of the outsourcing literature, this paper moves forward suggesting future avenues of research.
