Other items on the 'wish-list' include addressing how a multi-channel approach, such as including social networking, can be incorporated into CRM- something he said Oracle needsto 'figure out how that works' - and also the need to simplify and improve performance on OBIEE.

"I'm not hearing much about fusion so far and I do ask Oracle to figure out what is 'Fusion versus Siebel'? We need to have a way of joining those strategies together," he said.
