IT managers remain unconvinced of the value of electronic exchanges in improving efficiency in the supply chain.
In recent months a number of Internet exchanges have appeared in sectors such as car manufacturing, and are controlling more than $3 trillion in annual purchasing.
However, the Computer Weekly/Harvey Nash Big Question found 59% of IT managers did not agree the exchange would improve supply-chain efficiencies, or were unsure of their worth.
"Most of the benefits can be gained by re-engineering the purchasing process, reducing the number of suppliers and cutting back on levels of approval," one IT manager said.
Another IT professional was concerned that the exchanges could control prices and act as cartels.
Others were in favour of the exchanges as part of a wider effort to reduce cost.
