BPO originated with
manufacturing firms, such as
Coca-Cola outsourcing parts of their
supply chain. BPO can involve
back office functions like
human resources,
finance, and
accounting, or
front office functions such as
contact centre services. Some BPO services are
information technology-based, referred to as
ITES (Information Technology Enabled Service).
Knowledge process outsourcing (KPO) and
legal process outsourcing (LPO) are sub-segments. International BPO is termed
offshore outsourcing, while regional contracts are called
nearshore outsourcing. ==Industry size==
