WESTFORD, MA -- May 13, 2002 -- Teradyne's [NYSE: TER] Assembly Test Division, a global leader in electronics testing and production solutions announced today the implementation of its industry leading Teradyne SCE™ supply chain software by Hitachi Computer Products (America), Inc., a subsidiary of Hitachi America, Ltd. Teradyne SCE software is a manufacturing execution system used to reduce costs and accelerate products to market by optimizing collaborative manufacturing across a distributed, international, multi-company supply chain.

Teradyne SCE was implemented by Hitachi Computer Products (America) to provide the rigorous level of quality management required to support ISO 9002 certification and achieve the business profitability and growth goals associated with the introduction of several new products into production.

"We are very pleased with the support provided by Teradyne in implementing the SCE solution," said Larry Harvey, plant quality manager at Hitachi Computer Products (America). "It was up and running with minimal disruption to our production operations."

Teradyne SCE enables Hitachi Computer Products (America) to automatically correlate in-process quality information with work-in-progress and product genealogy data, improving collaboration between all groups in the supply chain and accelerating the new product introduction process for the company's configuration-to-order (CTO) manufacturing operations.

"The applications of the SCE solution are far-reaching," continued Harvey, "we originally implemented it as an inward facing solution for process improvement - which it performs very well, but once we got it up and running we found it actually provides even greater value as an outward facing solution to improve customer responsiveness. "

"Teradyne SCE enables discrete manufacturers to meet their business objective of minimizing inventory and improving customer satisfaction by providing real-time shop floor information to manufacturers and their partners via the Internet," said Ron Lindell, manager of Teradyne's supply chain execution software group. "Teradyne SCE also increases manufacturing throughput by identifying production bottlenecks in real-time. It decreases time to market by electronically managing the implementation of engineering changes, an operation that is essential for manufacturers of highly-engineered products."

About Teradyne SCE

The latest version of Teradyne's industry-leading collaborative manufacturing execution system, Teradyne SCE 2.1, contains many new features designed to make manufacturers in the high-tech, automotive and aerospace industries much more productive and efficient. For example, tightly integrated statistical process control (SPC) chart display and supply chain event alarming functionality means that data is collected once in Teradyne SCE and then used many times - eliminating separate data collection points for each application. Process lot and panelization support means that users can start and complete multiple shop floor control numbers with a single bar code read. Single screen non-conformance functionality provides quicker and more accurate non-conformance data entry and tracking non-across multiple levels of assemblies and sub-assemblies.

Java 2 Enterprise Edition architecture

Teradyne SCE™ easily integrates with other factory and corporate information systems by using industry standard XML interfaces and provides the lowest total cost of ownership through a 100% browser based thin-client and a high performance Java 2 Enterprise Edition (J2EE) application server, providing unparalleled modularity, performance, and scalability.

Teradyne's highly skilled manufacturing consultants ensure the quickest time-to-benefit for our clients manufacturing supply chain execution projects.
