Concerned about a public backlash about outsourcing in the wake of failed government IT contracts and other struggling outsourced projects, the National Outsourcing Association has launched a campaign to try and win back support for putting out work to external providers.

The National Outsourcing Association (NOA) has launched its Outsourcing Works campaign to "fight back against the negativity surrounding the sourcing industry following recent high profile failures".

It says Outsourcing Works will "unite the industry into one coherent voice that will elucidate the value that outsourcing brings to the UK, both in terms of job creation and efficiency gains".

The NOA claims the UK outsourcing industry is the second biggest employer in the UK economy, employing over three million people. "Although the NOA is aggrieved at the recent lambasting of our industry, we understand the need for outsourcing to prove its worth", it said.

The NOA said the public wanted to see evidence of the "macro-economic advantages that outsourcing brings", such as its track record of job creation and its positive contribution to the UK economy, which is what the campaign will aim to do.

The campaign will also involve the distribution of best practice guides and the NOA aims to work with the government to help reduce youth unemployment. There will also be an Outsourcing Works Symposium in June 2013.

NOA chairman Martyn Hart said, "One very high profile deal goes awry and outsourcing is squarely back under the microscope. Outsourcing only arouses interest when it goes wrong."

Hart said, "Of the hundreds of outsourcing deals that make up the Olympics, only one gets a mention [the failed G4S Olympics security contract]. To combat this depredation of our industry and address misunderstandings, the NOA is calling upon the entire outsourcing industry to champion the fact that Outsourcing Works."

Three police authorities in the UK are still considering outsourcing their organisational support services to G4S, despite it coming under fire for under-supplying security staff for the London Olympics.
