Rapid Implementation Enables Leen Bakker to Focus on ROI initiatives

JDA(R) Software Group Inc. (Nasdaq: JDAS) Thursday announced that Leen Bakker Groothandel B.V., the Holland-based value furniture and floor coverings retail division of US$2 billion Blokker Holdings, one of the largest privately-owned European retail companies, has implemented Open DataBase Merchandising System(TM) (ODBMS(R)) in just eight months.

Leen Bakker, which operates 150 superstores throughout the Netherlands and Belgium, licensed the JDA Portfolio(TM) client/server merchandising application in first quarter 2001.

ODBMS is part of Leen Bakker's massive business transformation IT project that will support its European expansion plans. In addition to replacing its core merchandising engine with ODBMS, the retailer also implemented POS, financial, human resource and other third party operational systems.

Leen Bakker went live with these systems using a "big bang" approach in order to efficiently operate its entire supply chain, from store order to store-delivery and purchase ordering to receiving in the warehouse. ODBMS was fully operational to run Leen Bakker's business from the moment that the retailer switched off its old legacy system.

Commenting on the retailer's aggressive implementation of ODBMS, Erwin Baarends, Leen Bakker's director of logistics and information communications technology, stated, "Large scale IT projects often carry on for two or more years and lose purpose and credibility.

"What distinguishes our project is that everyone involved within Leen Bakker and JDA successfully focused to complete this implementation to plan and to budget."

Baarends noted that Leen Bakker achieved success by honing in on ODBMS' core capabilities rather than spending time implementing "bells and whistles."

"JDA's proven implementation methodology and the consultants' in-depth understanding of our unique requirements enabled us to leverage key ODBMS functionality to help us achieve our immediate goal of improving efficient product flow and stabilizing supply chain processes."

"We are pleased to welcome Leen Bakker to our growing list of JDA Portfolio clients who have implemented and are successfully operating their business using our sophisticated solution.

"While there are many unfortunate examples of long, difficult and costly implementations reported in the industry, JDA continues to demonstrate its ability to deliver advanced capabilities in the most cost effective and timely fashion. We don't believe that anything less is acceptable in today's challenging and dynamic environment," stated JDA President Hamish Brewer.

"Leen Bakker's ability to rapidly implement and adopt ODBMS into its business practices is unquestionably impressive," added Bob Swanson, JDA's regional managing director. "This achievement underscores the paramount importance that retailers worldwide are placing on `quick hit' ROI initiatives and business benefits.

"By combining the broadest suite of integrated best-of-breed applications, with our no-constraints architecture and modular implementation engineering approach, our Portfolio solution offers the highest scalability and price/performance on the market today."

Leen Bakker is fully operational to support JDA's ODBMS and is operating it on the Microsoft Windows platform at the Desktop as well as at the Enterprise Server.
