Business process outsourcing (BPO) continues to evolve into a global matrix of services, locations, and providers that extend opportunities for financial services institutions (FSIs) to change and improve operational excellence through access to deeper domain expertise and finer-grained offerings. Large-scale BPO providers have depended on growing contracts with existing customers, a practice that ensures short-term success but is challenged by future Web 2.0 flexibility. Financial services institutions are finding a rapidly expanding set of sourcing options, locations, and structures. However, these will make BPO decisions both more difficult to make and more crucial to get right.
