The examples of this BPMN tutorial are based on the contributions we made to the document “BPMN 2.0 by example”, the BPMN tutorial provided by OMG ( Download as PDF).Example of business process modeling of a process with a normal flow with the Business Process Model and Notationīusiness process modeling ( BPM) in business process management and systems engineering is the activity of representing processes of an enterprise, so that the current business processes may be analyzed, improved, and automated. However, we do not recommend it: 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). You could always draw your diagrams from top to bottom instead from left to right – the BPMN 2.0 standard does not forbid it.

More on this later.įAQ: Is it obligatory to draw BPMN diagrams horizontally? What if I prefer to draw them vertically? We only sometimes abandon this practice with sub-processes. We always create our models with start and end events for two reasons: first, that way it’s possible to determine the process trigger, and second, you can describe the final status of each path end. The same is true for end events, which require start events. For this reason, we use the and make the passive in voice, so we write “hunger noticed.” BPMN does not require you to model start and end events for a process – you can leave them out – but if you model a start event, you must model an end event for each path. We would say “acquire groceries,” for example, not “first take care of shopping for groceries.”Įvents 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). When naming tasks, we try to adhere to the object-oriented design principle of using the + pattern. After that, someone will eat the meal and have his or her hunger satisfied.

The result is that someone must shop for groceries and prepare a meal. This diagram shows a simple process triggered by someone being hungry.
