Accenture is the best outsourcing service provider in the world for the fifth year running according to outsourcing profession group The International Association of Outsourcing Professionals (IAOP).
The IAOP ranks the top 100 outsourcing firms that go through the application process and judging. The top 10 also features Infosys (2nd), HCL (3rd), Wipro (4th), Capgemini (8th) and CSC (9th).
The ranking revealed that the outsourcing industry is growing, with average revenue for 2012 Global Outsourcing 100 providers at $1.6bn, with a growth rate of 6%.
The ranking also revealed some of the smaller but faster growing companies, many of which are in lower cost destinations, such as Asia, the Middle East and Eastern Europe. China-based Bleum was ranked 77, Scicom of Malaysia 79, Egyptian company Xceed was 81 and Auriga in Russia was ranked 85.
Vineet Nayar, CEO of India's fourth largest outsourcing company, HCL Technologies, warned in 2010 that China will eventually replace a lot of the work being done by Indian firms. That Chinese workers cost less removes a traditional advantage of India, said Nayar.
Meanwhile, KPMG was named the best outsourcing advisor with other top ten rankled firms including Deloitte (2nd), PwC (3rd), Alsbridge (4th), Ernst & Young (5th), PA Consulting Group (9th) and Booz & Company (10th).
