HR outsourcing (also known as HRO) is the process of sub-contracting human resources functions to an external supplier.
Reviews of business processes have led many organisations to decide that it makes business sense to sub-contract some or all non-core activities to specialist providers.
HR, as a non-profit centre, is an obvious candidate for outsourcing.
Outsourcing human resources or some of its processes to an external provider is a major business decision as, while it may be cost-effective, it introduces new elements of risk.
