SAP Developer Network Blogs - BPMN or EPC? provides an overview of both business process modeling languages, with the author showing his bias (correct IMHO) with the more detailed description of BPMN. BPMN is closer to what regular business people know as flow charts, so I think it's much more easily adopted. The support for BPMN in ARIS is very limited, so much so that it can't really be used if you are going to take advantage of the full capabilities in ARIS (automatic relationships between objects, like roles and responsibilities for instance, or simulation). This is a shame. But if you are just adopting standards for modeling in your organization, it doesn't really matter what notation that you use as long as you standardize on one and educate the business through examples, training, etc. Once they start seeing them, they will understand how to read and, eventually write them, themselves.
