(Business Process Outsourcing) is the act of transferring some of an organization's repeated non-core and core business processes to an outside provider to achieve cost reductions while improving service quality. Because the processes are repeated and a long-term contract is used, outsourcing goes far beyond the use of consultants. If done well, BPO results in increasing shareholder value. The main difference between BPO and more traditional IT outsourcing is that BPO offers companies a way of achieving transformational outcomes much more quickly. In a typical BPO contract, a service provider takes over a specific corporate function.

Effective BPO encompasses much more than just changing who is responsible for performing the process. In BPO, the outside provider not only takes on the responsibility to manage the function or business process, but also re-engineers the way the process has been traditionally done.
