Oracle used to have EBS which competed primarily in SCM/Procurement (or ERP) domain.

They acquired the leaders in HCM (PeopleSoft) and CRM (Siebel) domains and combined them all (SCM, HCM, CRM) into a single (new) product called Fusion.

Their pitch also was - PeopleSoft and Siebel required people with different skill sets (PeopleCode for PeopleSoft, Siebel eScript for Siebel); but with Fusion, customization would not require any programming language knowledge and in the rare cases that it did, you just needed Java. This meant it was cheaper for enterprises. This was a big selling point for a lot of enterprises and helped them reduce their IT cost.
