Business Editors & High-Tech Writers

SCOTTSDALE, Ariz.--(BUSINESS WIRE)--Dec. 10, 2002

JDA(R) Software Group Inc. reported that Castorama Group, Europe's largest and the world's third leading do-it-yourself retailer, part of US$8.30 billion Castorama-Dubois Investissements (CDI), is implementing JDA Portfolio(R). GETINOR, the IT subsidiary for Castorama and BRICO-DEPoT store brands in Europe, will use JDA's integrated, best in class retail functionality and modular implementation approach to support its clients' ambitious international growth strategy. The retailer is currently implementing JDA's open Portfolio Merchandise Management(TM) software and several Portfolio Space Management by Intactix(TM) applications to support centralization of its operations and empower its corporate office with more advanced retail functionality proven to reduce out of stocks and inventory costs while driving service levels, turns, sales and margins.

Prior to its selection, Castorama conducted a benchmark to thoroughly test the JDA Portfolio solution. After awarding the contract to JDA in early 2002, Castorama and JDA spent another 60-90 days finalizing a definitive agreement and implementation plan before making the deal official in third quarter 2002.

"We selected JDA for its clear strategy for the future, international strength, proven success rate and the rich functionality of its integrated product suite. JDA's best in class product strategy mirrors Castorama's IT strategy," commented Philippe Meurillon, chief information officer of Castorama Group. "We were particularly impressed with the best practices in assortment, category, price and supplier relationship management that we'll be able to execute due to the integration between JDA's strategic analytic software and Portfolio Merchandising solution."

"We are thrilled to be working with Castorama on this huge multi-cultural, multi-lingual and multi-continent implementation of mission critical software," commented JDA CEO Jim Armstrong. "While the scope of this project is one of the most significant in retail happening today, I have full confidence in our shared commitment to successfully establishing an innovative, scalable and flexible IT infrastructure for this world leading retailer to fully leverage."

Castorama is implementing Portfolio Merchandising to run in an Oracle/UNIX environment to manage its operations in France. Future plans call for implementations at the Castorama and BRICO-DEPoT chains in Spain, Poland, Italy, Brazil, Germany, Belgium and Canada from 2003 through 2005.
