The global offshore outsourcing market for IT and business services exceeded $55 billion in 2008 and some estimates suggest an annual growth rate of 20% over the next five years. Furthermore, over 200 firms from the Forbes 2000 companies and 50 per cent of the Fortune Global 500 had offshored IT and business process activities through captive centres, making a total of about $9bn of business. The phenomenon of offshoring and offshore-outsourcing is certainly expanding. It has become increasingly important to understand the phenomenon, not least as a basis for suggesting what directions it will take, its impacts, how it has been conducted, and how its management can be better facilitated. This book offers a broad perspective on various issues relating to the sourcing of systems and business processes in a national and global context. The authors examine both the client's and the vendor's involvement in sourcing relationships by putting the emphasis on the capabilities that each side should develop prior to entering a relationship but also that they should develop as a result of their interactions with each other.
