The crime against BPMn that works.

What IBM Websphere Business Modeler does on modeling can be called a crime against the BPM notation, but it really works.

I found that the putting the "business item" over the connector lines is a very good thing. For simple process it helps a lot to understand what gets into a task and what it comes out.

Even that this may go against the BPMn standard, I think it works.
