Accenture and Siebel Systems Team to Offer Latest Customer Relationship Management Solutions to Governments Around the World

Companies Announce Alliance to Deliver Solutions Accelerating Public Sector Innovation and Enhancing Customer Satisfaction

WASHINGTON, D.C., and SAN MATEO, CALIF.,– Jan. 14, 2002 – Accenture (NYSE:ACN) and Siebel Systems, Inc. (Nasdaq:SEBL) announced today that they have signed an agreement to work together to bring CRM technology to public sector agencies, ministries and departments worldwide. The companies will focus on developing and delivering these government solutions, which Siebel Systems positions as “Constituent Relationship Management” applications, on a preferred basis to postal, tax and revenue management and entitlement program agencies.

“For governments and public agencies facing tighter budgets in the wake of the economic downturn and the likelihood of increased caseloads, Customer Relationship Management technology offers the promise of enabling governments to step up service levels while making operations more efficient,” said David Hunter, Accenture managing partner for the Global Government practice. “We’re pleased to team with industry leaders, such as Siebel Systems, to develop, deliver and help provide world class solutions to the government officials who are looking for answers to the challenges of improved service, increased efficiency, and constituent convenience.”

Accenture’s Government practice helps national and state public enterprises and education institutions transform to reap the rewards of the eEconomy. With a global practice dedicated to the dynamic government market and a strong alliance network, Accenture brings innovation, experience and in-depth industry knowledge to public enterprises as they strive to connect with their citizens and businesses.

Siebel Systems provides an integrated family of eGovernment Applications software that enable public sector organizations to create a single source of information that makes it easier to identify, interact with, and provide service to government agencies and their customers across multiple channels, including the Web, call centers, mobile agents, field offices, and partner organizations.

By combining the deep knowledge, global footprint and experience of Accenture with the rich functionality of Siebel eGovernment Applications, government agencies can increase functional performance while decreasing the total cost of ownership and time to market.

One of the early government adopters where Accenture incorporated Siebel eGovernment Applications into an eLicensing and ePermitting solution is the Florida Department of Business and Professional Regulation. Accenture and Siebel Systems also have successfully teamed to deliver joint solutions to the U.S. Department of Education, District of Columbia Office of Tax and Revenue, and the State of Michigan Department of Treasury where success requires greater customer service.

“Our alliance with Accenture is an integral part of our strategy to serve new customers and expand our government offerings globally,” said Mercedes Ellison, Vice President Alliances, Siebel Systems. “Our close relationship with Accenture, forged over many years of working together, positions us to jointly make a significant contribution at the federal, state and local levels of government. This is a tremendous opportunity for Siebel Systems and Accenture to provide unique and comprehensive solutions comprised of world-class eGovernment applications and implementation services.”

Accenture recently won the Siebel Systems 2001 Partner Award of Excellence in North America and Europe for delivering 100 percent customer satisfaction, demonstrating strong organizational cooperation, and showing a commitment to growing the Customer Relationship Management market.
