According to a survey conducted by TPI, the leading global sourcing advisory firm, companies have reduced their spend on IT services and business transformation by almost one fifth by turning to outsourcers, thus saving $50 bn.

The firm surveyed 120 companies it had advised on sourcing over the last five years. TPI found its clients saved on average more than 33 per cent. After one-time and ongoing management expenses, the savings averaged more than 17 per cent.

According to TPI chairman and CEO Michael Connors the majority of businesses, 60 per cent, said that reducing costs was "their number one reason for implementing sourcing strategies".

Last year Europe became the world's highest spender on outsourcing, with companies based in Europe spending more on IT outsourcing than those based in any other region of the world.
