In the early days, BPO usually consisted of outsourcing processes such as payroll. Then it grew to include employee benefits management. Now it encompasses a number of functions that are considered "non-core" to the primary business strategy.Now it is common for organizations to outsource financial and administration (F&A) processes, human resources (HR) functions, call center and customer service activities and accounting and payroll.These outsourcing deals frequently involve multi-year contracts that can run into hundreds of millions of dollars. Often, the people performing the work internally for the client firm are transferred and become employees for the service provider. Dominant outsourcing service providers in the BPO fields (some of which also dominate the IT outsourcing business) include US companies IBM, Accenture, and Hewitt Associates, as well as European and Asian companies Capgemini, Genpact, TCS, Wipro and Infosys.(kalki382)
