Siebel vice president Keith Raffel said the technology was important to a number of industries, including financial services, health care and high tech.

"Its important to know what the relations are between people," said Raffel. "You want to know who somebodys best friend is, whos golfing buddies, fellow alumni of the same school. What contact networking lets you do is track those relationships."

Other features in this release include group calendaring and delegated task management. While Siebel CRM OnDemand will continue to synch calendaring and tasks with Microsoft Outlook and Lotus Notes e-mail clients, Raffel said these features are intended for customers who dont want to use their e-mail client but work within Siebels product for calendaring and tasks.

There is also a new segmentation wizard for managing and tracking the effectiveness of marketing campaigns.

"Its multidimensional segmentation," Raffel said. "It gets the right marketing message to the right people. The targets can be within CRM OnDemand and from outside databases."

In addition, this release contains performance improvements that have increased response times by 15 to 25 percent, according to Raffel.
