Oracle Siebel CRM and SAP CRM still offer the most complete solutions, with improved usability. SAP has been steadily working to fill out its CRM offering, resulting in end-to-end process integration support that no longer comes at the expense of missing CRM functionality. Meanwhile, Oracle Siebel CRM is still the most full-featured CRM solution, with a breadth and depth of functionality for many industry verticals. Both vendors have moved to address key complaints: poor usability, high cost, and long implementation times. Siebel 8.1 features the Siebel User Interface, which can be highly personalized and is task-driven. The SAP CRM 7.0 UI is flexible to support varying roles and offers drag-and-drop personalization that allows any section of any page to be rearranged by the end user. Both vendors are working to lower total cost of ownership (TCO) for their customers by introducing more preintegrations with other solutions from within their respective corporate families and offering “rapid implementation” methodologies and tools to reduce upgrade costs.
