MatrixOne to Host Webcast on Synchronous Product Development

WESTFORD, Mass.--Oct. 1, 20052, 2005--MatrixOne, Inc. , a leading provider of collaborative product lifecycle management (PLM) solutions for the value chain(TM), today announced that it will host a webcast focusing on the challenges that electronics/high tech companies face when implementing a "design anywhere, manufacture anywhere" (DAMA) strategy. The webcast will feature a presentation by Mike Burkett, vice president at AMR Research, who will use his years of experience in the PLM market to share with participants the latest trends and challenges.

In this webcast, participants will learn how improved integration between software, semiconductor, PCB and mechanical design disciplines is essential to the future success of technology companies--as they can no longer afford the costly and time-consuming practice of compiling and managing this information in separate locations, using separate methods. Products need to be brought to market faster than ever before, and a more efficient, better integrated approach is needed.

MatrixOne will show how a PLM-based synchronous product development solution can solve the problems faced by these technology companies, consolidating mechanical, electrical and software design content into a single definition in the engineering bill-of-material; eliminating organizational barriers between systems, design and manufacturing engineering; propagating any and all design changes to affected manufacturing plants in real-time; and securely managing the product supply chain's product responsibilities.

What: Free webcast entitled "Synchronous Product Development for High Technology Companies"

When: Thursday, October 13, 2005 at 4:00 pm ET

Who: Andrew J. DeTolla, director of product management for MatrixOne will conduct the webcast, featuring a presentation by Mike Burkett, vice president at AMR Research.
