Sorry – I’m not familiar with the Catalyst approach – maybe someone else here is?

Unfortunately, I don’t have any experience with the Rummler Brache approach, so can’t give an experienced-based opinion. I also searched the web for tutorials or examples of RB diagrams – but couldn’t find any (not that there are many BPMN examples either).

Does RB allow for the looping constructs and more expressive decisions (gateways) that BPMN supports? The only RB diagram I saw looked like a simple flowchart that had been mapped into swimlanes.

I must have missed the BPM bus. I’ve always used the Rummer Brache notation which is supported in Visio and comes along with their book on “managing the white space in the organizaiton.”

From your experience, what’s the significant difference (if any) in BPM and Rummler Brache for process modeling?

I’ve recently talked to both a BPM vendor and a Business Process Analyst. What really struck me in the conversation is that they deal in at a much higher process level. From this and some papers from Gartner, I’ve learned very little of BPM ends up at the level of a traditional use case.
