Re: Resources displayed on Business Process Models? 

Nerhesi:

The fact that BPMN and Activity Diagrams are poor choices for documenting flow of resources or data becuase of all the resulting complexity is  a significant real world problem that one will not find in any book.  A common complant of mine is that people who popularize methodologies and write books typically seem to have no hands-on experience with complex systems.

But, again, data flow diagrams are not just for documenting the flow of data.   This is a vey common misunderstanding.  The flows can be of ANY process input or output including physical part or materials.

What data flow diagrams offer is the opportunity to document flow of resources/data/etc at the higher levels - and flow of control/sequence at the lowest levels.   Doing such makes sense in that at the higher level, manual/automated systems, especially larger scale ones, have no sequence.  And by postponing flow of control/sequence to the lowest level, we do not result in creating diagrams that are so complex that it is impossible to fiigure out where our errors are at.

Re: Resources displayed on Business Process Models? 

Hi Sam,

It looks to me like your architect is trying to get the whole solution in one diagram. He/she is wrong. He/she may also be referring to more of a BPMN diagram whereas it sounds like you are doing UML activity diagrams. Basically, he/she is wrong. So fight him/her.

And I can't help making one more comment. In your simple example your actors are the applicant and the clerk. A system cannot by definition be an actor interacting with itself. Look at the activities you listed. They are clearly for one or the other of those actors.

Good luck with the fight!

Kimbo

Business Process Modeling Improves Administrative Control. His idea was that techniques for obtaining a better appreciative of physical control systems could be used in a parallel way for business processes.

Re: Resources displayed on Business Process Models? 

 Part of me says "give it a try and learn from the experience."  Part of me says "keep it simple."

Most of me says "Who is the audience of the document and what do they want to get from the content?"

Re: Resources displayed on Business Process Models? 

Brilliant stuff, man! What you have to say is really important and I am glad you took the time to share it. A business process will typically produce one or more outputs of value to the business, either for internal use of to satisfy external requirements. An output may be a physical object such as a report or invoice, a transformation of unprocessed resources into a new arrangement (a daily schedule or roster) or an overall business result such as completing a customer order.
