From my experience, I have seen tons of BPMN models modeled in Visio / Signavio / ARIS and the user expects these models to execute on a BPMN 2.0 engine.  Alas, execution is when the real WYDIWYE challenge comes out. (There are tools that compile process models to other execution languages, for example to Java. )   It’s quite likely that unless you have severely limited your modeling richness, that your compiler will reject your process model! Does your tool truly support WYDIWYE?  Which is to say, does the product you are using support your business process pattern?  Or are you limited in the patterns you can choose to run your business?

Maybe we should call the feature in question “WYCDIWYE”, where the “C” stands for “can”, as in “What-You-Can-Draw-Is-What-You-Execute. Which workflow patterns does your tool support?

Regardless of political affiliation, where modeling freedom is concerned, Roubroo users can all quote Barack Obama – “Yes we can!”
