CAMBRIDGE, Mass.--(BUSINESS WIRE)--Nov. 18, 2002

ATG(R) (Art Technology Group, Inc., Nasdaq: ARTG), a leading developer of online CRM applications for commerce, portals and relationship management, today announced that the American Heart Association (AHA) has successully launched its science professional site using ATG Portal. This implementation marks the beginning of the second phase of AHA's ongoing program to transform its online initiative into a more customer-centric channel. AHA had previously purchased ATG Commerce, which was used to launch the new corporate AHA Web site last fall.

The new corporate Internet site replaced a static site that lacked a centralized database and the functionality to tailor content to the organization's core audiences, including the general public, patients, donors, public officials, healthcare providers, and researchers/scientists. As the organization began to revisit its Web strategy last fall, AHA officials realized that driving content specific to each of these segments required a scalable technology platform that combined robust personalization technology with a flexible architecture.

"As an organization whose goal is to provide information on the prevention and treatment of heart disease and stroke, our online presence didn't allow us to reach out to our audiences individually. We needed a solution that would allow us to improve our ability to provide our audiences with practical and timely information," said Dave Neal, senior manager, Web operations digital strategies, American Heart Association. "By choosing to deploy ATG Portal, we are able to disseminate those valuable resources to each of our customer segments while at the same time knowing that we won't be pulled into a cycle of regularly reinvesting in new technology."

With the deployment of additional phases of the initiative, AHA will increase its use of ATG's Scenario Personalization as well as expand the commerce capabilities of the AHA Web site. Users currently are able to make donations online and in the future will be able to register for conferences and order subscriptions through the site.

"The most challenging aspect of bringing health-related services to the Web is trying to recreate the personal relationships synonymous with traditional healthcare services. Attaining these levels of personal interaction online requires the ability not only to know who your customers are but to know what information matters the most to them," said Matt Price, vice president, product marketing, ATG. "By leveraging ATG Portal in this second phase, the American Heart Association has set the wheels in motion for it to maximize the potential of its online initiatives."
