ATG Insight 2004

SCOTTSDALE, Ariz.--(BUSINESS WIRE)--Feb. 23, 2004

Executives From the World's Best Known Companies Congregate at ATG Annual Conference to Discuss How to Create the Ultimate Online Customer Experience

With

the Arizona desert serving as a backdrop and ATG customers like Best Buy, American Airlines, Nike and Merrill Lynch in the audience, ATG president and CEO Bob Burke offered an oasis today to companies seeking to provide the ultimate online experience for their customers. Burke formally opened the ATG Insight 2004 user conference at the Hyatt Regency Resort at Gainey Ranch in Scottsdale by describing the technology paradox for the 21st century.

"Consumers today have more variety that yields less satisfaction, while management has more strategic options that yield less value," said Burke. Speaking to a crowd of over 200 customers, industry analysts and pundits in attendance, he explained the fundamental demands for creating the complete customer experience and the missteps companies can easily make in their approach.

"The basic dimensions of personalization do not necessarily mean creating millions of unique offers for millions of different customers," Burke continued. "It means that we address the basic dimensions of experiences and people by focusing on events, context, individual involvement and personal meaning. It means that the individual is at the heart of a co-creation experience."

The opening day of the conference also featured a keynote address by bestselling author and entrepreneur Seth Godin. Attendees will also hear from ATG customers Neiman Marcus, TDC Sunrise, Intercontinental Hotels, Conseco, Novant Health, Movielink and Martha Stewart Omnimedia.

The ATG Insight 2004 conference runs through Wednesday and represents the premier gathering of experts and pioneers in creating the best online customer experiences. More than 200 ATG customers are on hand with ATG partners and industry analysts. Attendees participate in a series of business and technical sessions designed to foster an exchange of ideas around creating the ultimate online user experience using ATG's industry-leading customer experience platform.

"ATG Insight 2004 is a watershed event for ATG, our customers and the industry as a whole," said Cliff Conneighton, vice president of marketing at ATG. "Online commerce is a revenue channel that ATG customers know how to harness. The exchanges that are taking place here will ultimately help form the foundation for the next phase of doing business online and develop what the industry will view as how to create the ultimate customer experience."
