If we do not have such a process engine, but want to model the communication between the people involved explicitly, we would have to use a collaboration diagram as described in the next chapter.

In this diagram you can find the preparing steps a hardware retailer has to fulfill before the ordered goods can actually be shipped to the customer:. Hanxbuch that, someone will eat the meal and have his or her hunger satisfied.

We always create our models with start and end events for two reasons: Events refer to something that has already happened regardless of the process if they are catching events or as a result of the process if they are throwing events.


For this reason, we use the [object] and make the [verb] passive in voice, so we write “hunger noticed. However, we do not recommend it: You could always draw your diagrams from top to bottom instead from left to right – the BPMN 2.

The handbudh is true for end events, which require start events. These are the reasons:. Because we want to explicitly model the interaction between a pizza customer and the vendor, we have classified them as “participants”, therefore providing them with dedicated pools:.

Please note that there are no default semantics in this type of modeling, which means you can model collaboration diagrams to show the interaction between business partners, but also zoom into one company, modeling the interaction between different departments, teams or even single workers and software systems in collaboration diagrams.

In this example, we only used one pool and different lanes for the people involved in this process, which automatically means that we blank out the communication between those people: Tutorial Reference Examples Tool.

What if I prefer to draw them vertically? It is totally up to the purpose of the model and therefore a decision the modeler handbucj to make, whether a collaboration diagram with different pools is useful, or whether one should stick to one pool with different lanes, as shown in the previous chapter.


We would say “acquire groceries,” for example, not “first take care of shopping for groceries. This diagram shows a simple process triggered by someone being hungry.

Is it obligatory to draw BPMN diagrams horizontally? The result is that someone must shop for groceries and prepare a meal.

This example is about Business-To-Business-Collaboration. It is very uncommon, and experience has proven that people tend to understand the process flow better if it is described in the same way as written text from left to right, at least in the western world. If we had a process engine driving this process, that engine would assign user tasks and therefore be responsible for the communication between those people.

We just assume that they are somehow communicating with each hamdbuch. More on this later. We only sometimes hanrbuch this practice with sub-processes.
