Leading Online CRM Solutions To Be Enhanced

With New Publishing, Search, Analytics Modules and Integrations

Today, ATG (Art Technology Group, Inc., Nasdaq: ARTG) further establishes its position as a leader in the online CRM market with the unveiling of the ATG6 roadmap and the delivery of the initial Beta. This marks the latest milestone in the company's development of commerce and portal solutions that will help reduce the cost of conducting business by automating marketing, sales, and service on the Web.

ATG6 will offer major enhancements to ATG Commerce, ATG Portal, and the ATG Relationship Management Platform, as well as new ATG Integrations and three new product modules:

-- ATG Publishing for accelerating the creation, approval, and maintenance of
the assets required for successful, online CRM, such as catalogs, promotions
and service information

-- ATG Analytics for insights into sales trends and user behavior patterns

-- ATG Search for rapid access to online product and self-service information

"We originally selected ATG because of the Scenario Personalization capabilities that distinguish the company's solutions," said Lee Kunkle, vice president of technology, Restoration Hardware. "The new capabilities in ATG6 will help us keep our site content fresh while reducing our maintenance costs. This is just one of the many benefits that the new capabilities of ATG6 will bring us. We expect the new functionality to help us continue to drive a significant amount of new business, directly impacting our bottom line."

Featuring personalization capabilities to help increase customer yield, ATG Commerce is one of the most comprehensive online solutions for selling to businesses and consumers. By using new promotion and catalog management features along with analytics, non-technical staff will be able to drive more targeted sales activities to more buyers, more frequently.

"With the addition of modules for publishing and search, ATG will create an improved product in ATG6 that truly focuses on solving top issues for customers and significantly reduces costs across the board," said Alwin Magimay, partner at Accenture. "We look forward to continuing our very synergistic partnership with ATG and believe our joint customers will immediately reap the benefits of ATG6."

Working alongside ATG Commerce or independently, ATG Portal delivers comprehensive self-service capabilities that help reduce the cost of supporting customers, partners, or employees. ATG6 will provide significant enhancements to the ATG Portal solution, including publishing, search, and analytics, that help business users rapidly launch sales and service sites for specific partners, customers or internal projects.

"With these enhancements, ATG6 will be one of the most mature and comprehensive online CRM offerings available to businesses today," said Fumi Matsumoto, vice president of technology, ATG. "Through enhanced integration capabilities and the availability of the new modules, ATG6 will empower business users to drive even greater returns by selling to and servicing customers, partners, and employees online."

Details and Benefits of the New ATG6 Modules and Integrations

ATG Publishing -- Will automate the management and deployment of the assets, such as price lists, product catalogs, and service information, required for successful ATG online CRM initiatives. By simplifying publishing, businesses will be able to more easily address customer needs with appropriate content, which can drive greater click-thru and purchase rates.

ATG Analytics -- Will collect information from ATG solutions and structure it to help business users identify trends and customer behavior patterns. The ATG Analytics module also will include pre-built reports and datasets for business, finance, product, brand and site managers, increasing overall ease of use and return on investment.

ATG Search -- Will utilize keyword, advanced Boolean and parametric searches, as well as ranked results. One of the most frequently used features of any site, search will offer end users a means to find the information they need in the most efficient manner possible, increasing overall user satisfaction.

ATG Integrations -- A combination of software, services, and best practices that connect ATG solutions to enterprise business systems and enterprise assets, such as Siebel and SAP. ATG Integrations will allow for a unified view of a company's customers across online and traditional channels, enabling the company to provide the best possible service at substantially lower cost.
