We are in process of establishing enterprise business modeling standards. What is the recommended approach for process modeling EPC or BPMN? Any insights into why one is better than the other?
Your comments are highly appreciated.
Thanks in advance,

It depends what you want to accomplish. BPMN's scope is to map processes for execution but not for much more. If you want to do Enterprise Architecture or more advanced modeling, I would opt for EPC.
If you intend to execute your processes with webMethods, we recommend to create your business processes in VACD/EPC notation and then the EPCs will be transformed into a "logical BPMN" model that meets the wM standards.
For more info on the BPMN scope, you might want to have a look at the first of my article series "Leraning BPMN" at http://www.ariscommunity.com/users/roland-woldt/2010-11-28-learning-bpmn-1-what-bpmn.
In my opinion, it depends on what you want to achieve. In a SOA environment, BPMN 2.0 assists in identifying consumer, long running and short running processes as BPMN 2.0 symbols can be related to them. I also agree that the VCD should be used as the top level reference. We use the IAA reference architecture and at L1 and L2 we use the VCD, but from there we use BPMN. We also have a "split" between the process designs done by business analysts (non executable) using BPMN collaboration + BPMN process duagrams and then transforming them to executable processes by system analysts using BPMN process diagrams. With other words, transaction sub processes are modelled as executable process diagrams using BPMN process diagrams etc.
Both notations can work, but in our case, business users prefer BPMN and the BPM developers also prefer BPMN as it relates to our BPM solution.
You can minimise the differences between the two notations in ARIS. Using additional attributes and symbols, you can have different types of activities and events in EPC so not to miss that part from BPMN. Conversely, using Function Allocation Diagrams and additional extension mechanisms (for navigation etc) for BPMN2, you can have better results than you would with other BPMN tools. In both cases, the importance of a good governance process and rigorous modelling conventions is a must.
