Outsourcing advisory firm Orbys Consulting will place managers on short-term contracts in what the company has claimed is the first service of its kind.
The interim managers will offer advice on different aspects of outsourcing, including procurement, contract negotiation and how to manage existing deals.
Orbys will discuss which skills user organisations already possess and those that may need supplementing.
"In the past six months we have noticed that some of our clients have gaps in their skills, or lack staff for handling IT outsourcing but do not want to pay for a full-time member of staff to do it," said Alex Blues, director at Orbys Consulting.
He added that one area of particular demand for interim outsourcing managers is the "transitional" phase of the contract, between three months to one year after the contract has been signed.
Spending on outsourcing has risen steadily over the past few years as organisations look to drive down costs.
One of next big growth areas in outsourcing will be IT infrastructure management, according to a research paper by Deutsche Bank. The paper said companies could potentially halve their IT costs by outsourcing the management of their IT infrastructure to India.
