Dassault Systemes S.A. is furnishing under cover of Form 6-K a press release dated May 10, 2005, announcing their intention to form a strategic partnership with i2 Technologies, Inc.

Dassault Systèmes and i2
Form Strategic Partnership

Partnership developed to produce next-generation, 3D-based
sourcing solutions for collaborative PLM

Paris, France, and Dallas, Texas, May 10, 2005 – Dassault Systèmes (NASDAQ:DASTY; Euronext Paris: #13065, DSY.PA), the world’s leading developer of Product Lifecycle Management (PLM) solutions, and i2 Technologies, Inc. (OTC: ITWH), a leading provider of demand-driven supply chain solutions, today announced their intent to form a strategic partnership to jointly develop sourcing solutions based on Dassault Systèmes’ V5 platform for the CATIA, ENOVIA and DELMIA applications.

The intent of the partnership is to integrate sourcing throughout the product lifecycle, thus eliminating barriers between the engineering and sourcing communities and providing both sides with the opportunity to more effectively drive innovation and create value.

“We believe this partnership will define a new, collaborative way to integrate sourcing into product innovation and PLM,” said Bernard Charlès, president and CEO, Dassault Systèmes. “By partnering with a visionary in supply chain management, Dassault Systèmes intends to define the convergence of the PLM and SRM (Supplier Relationship Management) spaces to support our networked global customers.”

“We believe this is a great opportunity for i2 to continue to enhance and grow our expertise in supplier relationship management with a world-class PLM company such as Dassault Systèmes,” said Michael McGrath, i2 chief executive officer. “We believe this partnership can provide our customer base with an enhanced roadmap and growth path for the future.”

The joint offering will be designed to offer cross-functional visibility and unmatched collaboration, bringing sourcing considerations to the engineer’s desktop, and engineering criteria and 3D digital mockup to the sourcing specialist. The solutions will provide benefits such as:

  Ability to design for supply. Engineers will be able to optimize design by taking into account part-sourcing information such as obsolescence, availability and companies’ sourcing preferences early in the design cycle.
  Enhanced re-use management. Companies will be able to manage a cross-functional enterprise catalog, fully immersed in the 3D design environment, by combining engineering and sourcing information. This will give engineers the ability to evaluate and compare components based on functional engineering specifications as well as on cost, vendor preference, lead times, geographic regulations, and other sourcing characteristics.
  Optimized component and subsystem lifecycle management. Companies will lower product support risks because they will be able to evaluate all risks (technical, vendor, availability) before committing to final changes.
  Converging engineering and sourcing processes. All criteria can be considered in advance, meaning fewer iterations between sourcing and engineering, less rework, and better collaboration. Sourcing analysts will be able to visualize, manipulate, test and simulate components before buying.

“Truly integrated PLM and sourcing solutions drive better collaboration between engineering and sourcing, leading to higher part re-use and more consistent part usage,” said Leni Kaufman, vice president and CIO, Northrop Grumman Information Technology/Internal Information Services. “This is something that should be interesting to any company that designs and manufactures products.”

“Enterprises aligning sourcing and engineering earlier in the product development cycle have reported 18% reductions in product costs, 10% to 20% improvements in time-to-market cycles, and more than 20% improvements in initial product quality,” said Tim Minahan, senior vice president of Supply Research for Aberdeen Group. “Combining the strengths of i2‘s sourcing and Dassault Systèmes’ collaborative engineering capabilities should deliver a compelling platform to optimize product costs and accelerate innovation capture and new product introduction cycles.”

The next-generation sourcing solutions will be developed in a dedicated competency center hosted in a new i2 subsidiary. This joint competency center will bring together i2‘s domain expertise and core SRM components along with Dassault Systèmes’ V5 platform and PLM expertise. As a part of the long-term partnership, i2 will convey control of the competency center to Dassault Systèmes for approximately $10 million once certain conditions are met. i2 will then continue to provide SRM component upgrades and sourcing expertise and will work jointly with Dassault Systèmes to define the scope of the project. i2 will also continue to market and sell its SRM solutions and support its customers.
