What is a Swimlane Activity Diagram?
A Swimlane Activity Diagram, also known as a Swimlane Diagram or Cross-Functional Flowchart, is a visual representation used in business process modeling to depict the steps and interactions within a process involving multiple parties or departments. It divides the diagram into “swimlanes,” which represent different entities, roles, or departments involved in the process. Swimlane diagrams help clarify responsibilities and interactions within a complex workflow.
Here’s how a Swimlane Activity Diagram typically looks:
- Horizontal / vertical lanes: These represent different participants or departments involved in the process. Each lane is responsible for specific activities.
- Activities: These are the tasks or actions that need to be performed within the process. They are represented as rectangular boxes and are placed within the appropriate swimlane to show which participant or department is responsible for each activity.
- Arrows/lines: These indicate the flow of the process, showing how activities are connected and the order in which they occur. Decision points and conditions can also be represented with arrows.
