SAN MATEO, Calif.--(BUSINESS WIRE)--Sept. 17, 2002

Siebel Systems, Inc. (Nasdaq: SEBL), a leading provider of multichannel eBusiness applications software, today announced that CompUSA, America's largest computer superstore retailer, has standardized on Siebel 7, the seventh major release of Siebel eBusiness Applications. CompUSA has deployed Siebel Call Center 7 and is benefiting from new functionality, improved integration and scalability, and lower overall cost of ownership.

CompUSA, Inc. is the nation's leading retailer and reseller of personal computer-related products and services. Founded in 1984, it now operates approximately 218 superstores in 84 major metropolitan markets. Siebel 7 introduces key new functionality and significantly improved performance to more than 300 service professionals at CompUSA, enabling the company to provide enhanced customer service and support. By migrating its legacy systems and upgrading its current call center system to Siebel 7, CompUSA will create a more centralized operating system and streamline performance. An additional concern is integration and with Universal Application Network, a standards-based approach to the design and development of cross-application business processes launched by Siebel Systems, CompUSA will support customer-centric, end-to-end business processes that span multiple systems of record and business logic.

"Siebel 7's automatic upgrades and zero-footprint Web architecture will allow CompUSA to speed deployment time and significantly lower our total cost of ownership," said Scott Johnson, Director of IT Services. "By delivering this best-practice functionality in a highly flexible and scalable Web environment, Siebel 7 allows us to focus on offering our customers world-class service and support."

Siebel Call Center 7 will allow CompUSA to increase service profitability by managing customer interactions across multiple channels. The new Siebel Smart Web Architecture gives Siebel Call Center 7 a low-bandwidth, browser-based application that addresses agents' real-time needs and maximizes productivity. Inquiries can be routed to an available agent with the necessary skills to help increase customer satisfaction and improve agent efficiency, thereby lowering costs. Finally, Siebel 7 also brings business analytics capabilities across all applications to deliver relevant, up-to-the-moment intelligence to employees, partners, and customers.

CompUSA plans to roll out Siebel Sales 7 and Siebel Field Service 7 in the next few months. Siebel Sales 7 will help its sales professionals focus on the right deals at the right time, grow profitable relationships, shorten the sales cycle, and increase revenues. Siebel Sales 7 includes numerous forecasting enhancements and analysis across forecasts. With Siebel Field Service 7, CompUSA will achieve maximum service effectiveness through scheduling optimization, contract management, dispatch, and wireless messaging. These tightly integrated features of Siebel Field Service 7 enable field service organizations to respond quickly to customer needs.

Once the Siebel Field Service 7 migration is complete, next steps include the migration of CompUSA's homegrown help desk to the Siebel HelpDesk Online functionality. Additional future plans include giving CompUSA's retail customers and partners access to Siebel 7, enabling those groups to create their own service requests as well as track progress of their work orders.
