If the car needs to be both cleaned and repaired, both things happen. Also, if it needs to be repaired, it will be repaired. After that purchase, if the car needs to be cleaned, it will be cleaned. In this example of a business process model, our actor purchases a car. They could all be taken, or only one of them. We suggest using the event based gateway for a cleaner diagram.Īn inclusive OR Gateway specifies that one or more of the available paths will be taken. Either style is acceptable in the BPMN official spec. This alternative approach, while potentially easier to read, is also more verbose (Adding an extra task to the process). Once it is in the process, we would use a data based XOR gateway, as shown in the following example. We could also have modeled this by bringing the girl’s response into the process as data. If she says no, he will stay home and play XBOX games all night. If her response, a message that is external to the process, is yes, the actor rents a tuxedo and attends the prom. In this business process modeling example, our actor invites a girl to the prom. This will make more sense when we consider the example business process model.

The distinction is if the information required to make the decision is available within the process (use data based) or comes from an external source (use event based). When an event, such as an external message, causes us to make an exclusive OR (XOR) decision, we use a different XOR gateway. We also could have drawn the diagram as follows: The available data is the content of the mail (either junk or real). The first gateway represents the choice based on data available in the process. In our business process modeling example above, after opening the mail, the person will either read the mail (and then discard it), or discard it without reading it. We prefer to use the diamond with the ‘X’ in it. Whatever style is chosen, it should be consistent within the diagram and all diagrams. It can be drawn as an empty diamond, or as a diamond with an ‘X’ in it. The first thing to note is that this gateway can be drawn in either of two ways. This is the behavior generally assigned to the familiar diamond from flow charting. More than one path can not be taken – they are mutually exclusive, hence the name.

We have a link to the official version of the spec in our introductory post (we will update that link if and when the spec changes). This common convention allows people who are familiar with modeling, but new to a project to avoid learning a new diagramming language on each project or for each client. The BPMN specification is designed to establish a common language and convention for creating process diagrams. The diagrams can also help uncover requirements that might be overlooked without diagramming the processes.

These diagrams help identify the scope of a software project. Business analysts are often required to document as-is processes and to-be processes. We presented an introduction to BPMN diagrams last week.
