I wrote an article comparing the IBM  solutions  for Process Design and Modeling. It is very quick and visual  and the feedback is welcome.

 

I compared this products:

• IBM Websphere Business Modeler Advance 7.0 (WBM) (formerly Holosoft)
• IBM Filenet BPM Starter Pack (Filenet BPM) - Process Designer Tool 4.0.2.0
• IBM Websphere Lombardi Edition 7.1 (WLE) (formerly Lombardi Teamworks)
• IBM BPM Blueworks (only available as a Service) (formerly Lombardi Blueprint)

But I tried only to see this products from the perspective of the Process Analyst for Process Design and Modeling.
