ATG Expands Customer Care Offering.

CAMBRIDGE, Mass. -- Art Technology Group, Inc. (NASDAQ: ARTG):

--Licensed and OnDemand Solutions for Live Chat, Customer Intelligence, Offer Management, and e-Mail Response Management all Speed Issue Resolution, Personalize Responses and Create Dynamic Cross- and Up-Sell Opportunities

Art Technology Group, Inc. (NASDAQ: ARTG) whose licensed and on demand technology powers e-commerce sites and supporting e-marketing and customer care solutions for the world's most customer-centric enterprises, today announced that it has added powerful new functionality to the company's comprehensive customer self-service and agent-assisted customer care solutions. ATG's new and enhanced Live Chat, e-mail Response Management, Offer Management, and Customer Intelligence applications work together to deliver an integrated, consistent, and personally relevant multi-channel customer experience.

These new capabilities significantly broaden the multi-channel capabilities of ATG's customer care suite, add powerful new reporting and analytics tools, and bring ATG's unique and award-winning personalization and content targeting technology to the customer care agent. These enhancements both speed service resolution and also help companies find revenue-generating potential in their typically profit-draining customer care organizations.

The new capabilities in ATG's customer care suite include:

--ATG Live Chat -- a chat messaging application that gives customers another important channel to use when communicating with customer care agents. When seeking product information or answers to service questions, customers increasingly prefer the personal, live interaction that chat affords, and the ability to interact with an agent without leaving the Web pages they're browsing. As part of an integrated multi-channel service environment, ATG Live Chat offers capabilities that other chat applications can't match. With ATG, the chatting agent has an instant, full view of a customer's previous self-service, telephone, e-mail, and chat interactions, as well as to a top-rated knowledge base of answers to speed resolution. This blended interaction environment also presents detailed customer profile information and previous product order history. ATG Live Chat also uses ATG's offer management capabilities, described below.

--ATG Response Management -- a complete solution for managing customer e-mail sessions now also handles sessions from ATG Live Chat and SMS mobile devices. Interactions from any of these channels can be routed to the best available agent using rules that examine message content, source, queue length, customer profiles, agent skills, or other information. Agents can access a knowledge base and use pre-defined response templates to more quickly deliver answers or escalate to other agents. The application monitors the entire interaction process and creates supervisor alerts when service level goals are missed - for example, when an inbound email has not been answered within an hour. Customer interactions from all channels - self-service, telephone, email, chat or SMS - are all integrated, and the complete customer history is available to every agent.

--Offer management capabilities extended across the customer care suite -- enables organizations to make relevant and contextual offers to their customers via Web self-service, and to their agents during telephone, e-mail, chat or SMS Mobile interactions. Leveraging ATG's award-winning personalization, segmentation and content-targeting technology, agents see information and offers tailored to customer's segment, profile, purchase history, frustration level, and situation. For example, an agent chatting with a customer about a problem with an obsolete product can be prompted to make an upsell offer for a replacement product..

--ATG Customer Intelligence -- a completely integrated set of datamart and reporting capabilities that gives ATG customers the insights they need to fully understand their customers. By combining key data from ATG applications on outcomes (such as purchases, searches, escalations, click-throughs) with behavioral data from Web traffic analysis, and demographic data such as age, gender, and geography, ATG Customer Intelligence offers business and IT users a single source for monitoring the success of e-business. By tying together multi-channel data, users gain a more balanced look at the Web's role in converting leads to sales, or into the success of their efforts to drive customers to online self-service from expensive agent-assisted channels.

"Regardless of the size of their businesses, organizations need to provide a relevant and consistent multi-channel customer care experience or risk losing out to competitors," said Cliff Conneighton, senior vice president of marketing, ATG. "The goal of ATG's customer care suite is to ensure that consumers and businesses benefit from faster, richer and more manageable customer service interactions. Now, organizations have an even larger set of tools with which to resolve issues and satisfy customers more quickly -- and at the same time identify additional revenue opportunities. All of this functionality is available either as traditional licensed software or in a convenient, software-as-a service hosted environment."
