Business Process Outsourcing (BPO) is the process of a service provider managing various aspects of business activities: the people associated with the business process, the associated and underlying technologies and the IT support staff for an organization. It helps the organization focus on its core competencies, reduce operating expenditure and improve its bottom line. BPO offerings are basically categorized into two major categories, i.e. horizontal offerings (industry specific offerings) and vertical offerings (domain specific offerings).
