Uml Process / Questions re: BPMN 2.0 Diagram Interpretation
« on: June 26, 2015, 01:55:23 am »
I don't see a forum topic area devoted to BPMN specifically, so I am posting my BPMN questions here.  Please inform me if there's a more appropriate thread / sub-forum for me to post questions about BPMN.  BTW, I know this is an EA forum, and I do have specific questions pertaining to EA that I've posted in the proper threads.

Now for my question:  If a map exists with N number of DataObjects with the same name - e.g. Bob - with each one connected to a different activity via a data association (the intent being to show how one or more physical documents move through a business process), is the correct way to interpret that map that each DataObject named Bob is a separate, unrelated entity and that there are N number of separate "Bobs", each with data associated only to the activity to which an association is indicated?

My thinking is that the "correct" way to illustrate movement of an object/data through a process diagrammed using BPMN 2.0 would be to place the object on a diagram one time and then create the appropriate data input and data output associations between that one DataObject and each activity that requires it.

I know BPMN is not intended to document how DataObjects and information move through a business process, but that's what management wants to see and I'm trying to determine the "correct" or "best" way to illustrate that in my maps.

Thanks for any assistance.

Welcome to my nightmare, q.  Our "captain" is more like a private and is clueless as far as BPM goes; he understands enough to be dangerous.  No consultants or product training for my group.  We've already asked for some tool training and the silence spoke volumes.  Because of the way this company has chosen to implement this project, it's going to go south anyway.  Penny wise and pound foolish, like many U.S. companies.

Thanks, Q. I don't think I have that option. I have to use the tools I'm given.  Plus, the management of the group I'm in don't want to have to maintain multiple sets of diagrams in one tool, let alone two.

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.

Uml Process / Re: BPMN 2.0 Biz Process vs. Composite Activity

Thanks, Simon.  I am talking about a BPMN activity.

I have years of process diagramming experience with other methodologies, but am just starting out with BPMN and am learning it on the fly (trial by fire; no training and only the OMG 2.0 BPMN spec, a few of the highest-rated books (by Bruce Silver and camunda) on Amazon for reference, and all my colleagues know less than I do :o), so forgive me if my questions appear to be simplistic.

Judging from where things are in this company, it's going to be a long, long time before this place will be using BPMN to automate its business processes, if ever.  It's difficult to get people to see the value in diagramming processes by staying true to the BPMN spec.

The only real differences are the tagged values added by BPMN (and likely mimic the eye glasses/chain symbol for composite with a shape script).


If those are the only differences, why do the two elements behave differently with respect to sequence connectors and how they interact with simulaitons (or vice versa)?  :-?

I'm trying to learn the meaning and correct usage of a BPMN 2.0 business process element (eyeglasses in lower right corner) and the difference between that and a composite activity.  I haven't found anything really meaty in the EA help file and we're having quite the argument spirited discussion about whether and where to use a business process element vs. a composite activity element.

I've noticed a few things about the business process element:
  • You can automatically create a child diagram upon creation of the business process.
  • You cannot draw a sequence connector between an activity and a business process.
  • If you have a business process nested within another business process and run a simulation against the parent process, the simulation will not run against the child process.
Now for the composite activity:
  • Will not automatically create a child diagram upon creation of the composite diagram.
  • If you have a composite activity nested within a business process or a composite activity nested inside another composite activity, a simulation will run against all elements.
Thanks in advance for your help.
