Process Interaction and Collaboration

External Participants

External participants can be perfectly modeled with a collapsed pool - and hence be considered as a black box. The interaction with such "externals" can only be represented by messages flows, which always indicate an exchange of information.

Note
Sequence flows can never cross the border of a pool - but message flows can!

Usage of Message Flows

Message flows are used for communication between pools only. They are not used for internal communication as we have the sequence flow for this occasion. The other way around we cannot use sequence flows to communicate with other pools but rather use message flows.

Click on each example to find out what's correct.

Usage of Message Flows Example

Business Example - Let's Apply What You've Learned

Order Management

The process below shows a more realistic example of how to interact with external participants and also contains different elements you learned already in the course:

  • External participants & interaction
  • Expanded subprocess for summarizing task
  • with a cancel condition
  • Collapsed subprocess - and evaluating the result
  • Attached intermediate event (here: conditional event)
  • Starting message events
  • Usage of IT-systems (spoiler: next lesson)

Using all these different elements allows us, modeling an easy-to-follow order management process, which has even some exceptional condition with a loop in it.

When we show up to the present moment with all of our senses, we invite the world to fill us with joy. The pains of the past are behind us. The future has yet to unfold. But the now is full of beauty simply waiting for our attention.

Note
If you use this way of process communication, please keep in mind that both pools are self-contained and have their independent processes - including their individual goals.

Process Collaboration (Choreography Diagrams)

The supreme discipline in process modeling is, to model different processes and their interaction. However, there are some considerations as this is not always useful and can easily lead to the problem, the entire process model cannot be understood any more by other people.

We would only recommend modeling different processes in one model, when:

  • interaction on task level is important to show
  • the processes itself are not too complex
  • it's still "easy to follow" and not too overloaded

When we show up to the present moment with all of our senses, we invite the world to fill us with joy. The pains of the past are behind us. The future has yet to unfold. But the now is full of beauty simply waiting for our attention.
