Business Process Outsourcing (BPO) can be defined as the transfer of an organization's entire non-core but critical business process/function to an external vendor who uses an IT-based service delivery. By doing so, BPO helps an organization concentrate on its core competencies, improve efficiency, reduce cost and improve shareholders' value.

As below is top 5 reasons to outsource business process.

Reduce Operating Costs

Companies that try to do everything themselves may incur vastly higher research, development, marketing and deployment expenses, all of which are passed on to the customer. An outside provider's lower cost structure, which may be the result of a greater economy of scale or other advantage based on specialization, reduces a company's operating costs and increases its competitive advantage.

Improve Company Focus

Outsourcing lets a company focus on its core business by having operational functions assumed by an outside expert. Freed from devoting energy to areas that are not in its expertise, the company can focus its resources on meeting its customers' needs.

Free Resources for Other Purposes

Every organization has limits on the resources available to it. Outsourcing permits an organization to redirect its resources, most often people resources, from non core activities toward activities which serve the customer. The organization can redirect these people or at least the staff slots they represent onto greater value adding activities. People whose energies are currently focused internally can now be focused externally -- on the customer.

Make Capital Funds Available

There is tremendous competition within most organizations for capital funds. Deciding where to invest these funds is one of the most important decisions that senior management makes. It is often hard to justify non-core capital investments when areas more directly related to producing a product or providing a service compete for the same money. Outsourcing can reduce the need to invest capital funds in non-core business functions. Instead of acquiring the resources through capital expenditures, they are contracted for on an "as used" operational expense basis. Outsourcing can also improve certain financial measurements of the firm by eliminating the need to show return on equity from capital investments in non core areas.

Reduce Risk

Tremendous risks are associated with the investments an organization makes. Markets, competition, government regulations, financial conditions and technologies all change extremely quickly. Keeping up with these changes, especially those in which the next generation requires a significant investment, is very risky. Outsourcing providers make investments on behalf of many clients, not just one. Shared investment spreads risk, and significantly reduces the risk born by a single company.
