Bringing together theoretical and empirical studies from the Journal of Information Technology, this book provides a definitive guide to research discovered on the growing global sourcing phenomenon. Paying particular attention to Information Technology Outsourcing (ITO) and Business Process Outsourcing (BPO), theoretical chapters explore insightful ways of thinking about the different facets of outsourcing, and provide useful information to practitioners and researchers. Empirical chapters report the findings of 405 major research studies into the risks and successes of relationships between customer and vendor, the development of trust in these relationships, the factors affecting locations for offshoring, and specialized offshoring organizations such as captive centres. In this comprehensive study, the editors present an expert review of the historical development of this field, and offer analysis of emerging findings and practices for the future.
