Here I go again
If you have been involved in Siebel CRM projects over the past years, you might have come across some business analyst who mentioned the Siebel Business Process Solution Library (BPSL), which has been released as part of the strong business process strategy together with Siebel CRM version 7.5 in 2002.
Teaching the approach to analyze your business processes and align them with the out of the box functionality BEFORE you start customizing the hell out of your CRM app during the Business Analyst courses*, Siebel instructors all over the world were challenged to position the library NOT as a complete encyclopedia of all business processes that you can do in Siebel applications. To be honest, this would be a ridiculously small library given the vast functionality of Siebel CRM.
In contrary, the BPSL describes - that is at least mho - common best practice approaches to business processes which are (of course) supported in Siebel out of the box.
However, the BPSL has had a rich (including integration with Corel iGrafx and IBM Rational Requisite) but also difficult past and finally has emerged again on metalink3, Oracle's support portal for Siebel CRM customers. So if you have access to metalink3, you also have access to the link below.

*Note: The current Business Analyst training does not teach the BPSL.
