This document summarizes a student paper that examines factors that drive companies to backsource or move activities back in-house after outsourcing them. The paper identifies key reasons for outsourcing failures through a literature review, including expectation gaps, organizational resistance to change, loss of knowledge, intellectual property concerns, contractual issues, hidden costs, and inability of vendors to meet requirements. It concludes that companies underestimate how outsourcing impacts projects and that carefully considering details at the outset could help prevent backsourcing due to failed outsourcing arrangements.
