About a half-dozen Siebel CRM users interviewed at the Oracle OpenWorld 2006 applications and technology conference here said that Oracle has been slow to provide details on its pledge to integrate Siebel and Oracle products and to provide detailed information about its long-term plans for the CRM product line.

The US$5.8 billion deal closed earlier this year.

Julie Reeves, CRM leader for the office of the CIO at Electronic Data Systems Corp., is looking for a road map outlining Oracle's plans for the Siebel middleware products used at the Plano, Texas-based systems integrator.

EDS uses Universal Application Network middleware, which uses Web services to connect front-office Siebel applications to other software, and Universal Customer Master, which gathers information about a company's customers to be used for analysis.

EDS also uses Siebel CRM tools but expects a smooth growth path for those products, she said.
