Sainsbury claims the tool, which transfers the entire product development cycle to a website and keeps all parties involved in the process to a strict timetable, can slash the time to market by a third.
More than 2,000 products have now been developed on the site, involving 550 suppliers.
Total auction volumes at the exchange are set to break the $10bn barrier this year as buyers ramp up their usage of the procurement tool, said GNX boss Joe Laughlin. GNX members including Sainsbury, Metro and Carrefour conducted over 2,300 online auctions worth more than $1.4bn in the quarter ending March 31 more than doubling the volumes from the same period last year.
However, tools helping members improve service levels and reduce stock by improving data flow with their suppliers were also making headway, said Laughlin.
