Hierarchy of objects in BPMN 

Hi

In Information Eng. (James Martin), the activities have the hirearchy:

Function

Process

Elementary Process

What is the corresponding hirearchy in BPMN?

Is it like this:

Process

Sub Process

Task

Step

Thanks

Re: Hierarchy of objects in BPMN 

What do you mean by 'corresponding'? While the two use some of the same words, they are describing very different things, so you can't equate a level in one with the same level in the other.

Re: Hierarchy of objects in BPMN 

I agree with David... "Information Engineering" is set of techniques and approaches (think methodology) for designing and developing information systems.  BPMN (Business Process Modeling Notation) is just a notation for modeling business processes.  Pretty much any methodology which calls for documenting/modeling business processes could you BPMN as its notation.

Having said that, BPMN does not define a hierarchy per say.  When it comes to "things" that describe behavior/logic BPMN uses the generic term of "Activity" to refer to work that an organization/company does.  BPMN defines three types of activities:

  • Process
  • Sub-Process
  • Task

In addition, activities can be grouped together using one of the following BPMN concepts:

  • Pool - represents all the activities performed by a specific participant (organization, company, etc.) in the process.
  • Lane - a sub-partition of a pool, can be used to categorize activities within a pool (ex: activities performed by a given role, activities performed by a given department, activities supported by a given IT system, etc.)
  • Group - this graphical element, allows the business analyst to create any other types of grouping of activities for any suitable purpose.  A group of activities can cross lanes within a pool.

Of course, a process can contain sub-processes and tasks, and a sub-process can contain other sub-processes and tasks.

Is this what you were looking for?

I’ve heard “The End is Near!” for Business Analysts for almost 20 years.  Waterfall project management, with its need for formal requirements, is dead…a dinosaur…so 1990’s.  To be honest, that’s mostly true.  With the publishing of the Agile Manifesto in 2001 there was no need for a 2-inch-...
