The company for which I'm creating BPMN diagrams is just getting started with BPMN; my group is doing nothing with UML. In fact, our diagrams may never see the light of day as far as development goes. BUT... My managements wants one diagram that will be suitable for presentation to IT execs and business executives, yet also will be useful for developers and business process improvement folks. They want to be able to decompose a process into deeper and deeper layers to see more detail. That being said, I know BPMN is not a decomposition methodology, but perhaps there are techniques I can use to communicate what I need.
Is there a way I can visually illustrate in BPMN, without making executives' eyes cross, that a collection of shipping documents (electronic and/or physical) breaks down into a manifest, an air waybill, certificate of origin, etc. and show how some of this collection will go to one activity and some of it to a differnt activity? Would I need to create subclasses? If so, how would I illustrate visually within a BPMN diagram that SubClass A1 and SubClass A2 are children of SubClass A?
I might be on the opposite side of the world from many of you. As I write this, it's 1:37 PM Central Daylight Time on Friday, 12 June 2015, which is probably several hours behind you. Be that as it may, I won't be able to read or respond to any messages until 15 June 2015 in my location.
Thanks in advance for your suggestions.
