Business Process Model and Notation (BPMN) is a standard way to represent business processes graphically. Visio includes a template that contains the graphical elements described by the BPMN 2.0 specification, following the Analytic conformance class.
To find the right template to start from, go to File > New and, in the search box, type BPMN Diagram.
- For each step in the process you want to model, drag a shape from the stencil to the page, and connect the shapes as usual.
- The BPMN specification calls for three types of connectors: Sequence Flow, Message Flow, and Association. Connectors you add by using AutoConnect or the Connector tool are Sequence Flow connectors by default. You can change the type by right-clicking the connector and then clicking the type you want in the shortcut menu.
- For general information about connecting shapes, see Connect shapes by using AutoConnect or the Connector tool.
- Right-click shapes to set the attributes of each object.
- Every BPMN shape has some underlying data, or attributes. These attributes specify the appearance of the shape, as well as additional data associated with the shape. Right-click the shape to view and change the main attributes in the shortcut menu.
- Validate the workflow against the BPMN rule set.
- On the Process tab, in the Diagram Validation group, click Check Diagram.
- Fix any problems that appear in the Issues window.
Validation checks only the graphical elements; it doesn’t check the accuracy of attribute values. For more information about validation, see Validate a structured diagram.
Some visual changes that can be performed on shapes in flowcharts and other diagrams are not allowed in BPMN diagrams, because they are not allowed by the BPMN 2.0 specification. For example, you can’t change the appearance of a sequence flow line to a grey dashed line, because it would look like a message flow.
