London--The WorldWide Retail Exchange named textiles executive Colin Dyer as its CEO. Dyer was formerly CEO of Courtaulds Textiles plc, which means he is coming from a supplier rather than buyer company. So-called coalition e-hubs seem to be taking greater care not to come off as being strongly buyer-focused following ongoing delays and problems at auto marketplace Covisint. WWRE was founded earlier this year by retail giants including Best Buy, Gap Inc., JCPenney Co. Inc., Albertson's and Kmart Corp. It is using technology from IBM Corp., i2 Technologies Inc. and Ariba Inc.
