A taped message from Oracle CEO Larry Ellison greeted attendees at Siebel Systems' Monday kickoff for its annual user show, a conference shadowed by Siebel's deal last month to sell itself to former rival Oracle for around $5.9 billion.

Siebel executives had planned to use the CustomerWorld show, in Boston, to discuss their customer relationship management development roadmap and to launch Siebel's new line of prebuilt software components, called Siebel Component Assembly (formerly Project Nexus). Oracle threw cold water on Siebel Component Assembly last month at its own user conference, however, where executives including Ellison said Oracle would not seek to preserve code from its acquired applications as Oracle develops the next generation of its applications software.

Siebel Component Assembly still launched as scheduled on Monday, but Siebel's executives focused their keynote presentations on the company's broader strategic vision. Siebel CEO George Shaheen touted the company's industry-leading 3.7 million active users of its CRM software, while Siebel products head Bruce Cleveland outlined the company's plans to unify its Enterprise, Component Assembly and CRM OnDemand software user interfaces into one common interface for all of its applications. The company's goal is to make its products flexible enough to match its customers' varied needs and business processes, an approach Siebel has dubbed "customer adaptive solutions."

"Over time, all of our solutions sets will be offered on all platforms," Cleveland said. In describing the company's user-interface plans, he commented, "We're going to integrate the user interface so tightly with Microsoft Office that Microsoft Office can actually serve as the primary interface for any user."

While Shaheen touched only briefly on Siebel's future within Oracle's rapidly expanding empire, he reassured attendees that Siebel's CRM vision will be the reigning one at Oracle. Ellison echoed that in a brief, recorded message played during CustomerWorld's opening session. "[Siebel's] applications will be the foundation of Oracle going forward," he said.

One customer attending the opening session, BlueCross Blue Shield of Illinois Application Team Lead Sreekanth Uppaluru, said he wished Siebel's executives had spoken in more detail about the upcoming Oracle acquisition. He came to the show hoping for information on product road maps and on how customers will be affected by the deal.
