What type of flow in BPMN connects objects within the same pool?

In Business Process Model and Notation (BPMN), the flow that connects objects within the same pool is represented by smooth-lined arrows. These arrows depict the sequence flow, which indicates the order of activities or events that occur within a specific process. This type of flow is crucial for understanding how tasks and events relate to one another within the context of a single organizational entity or a particular business process.

Smooth-lined arrows provide clarity and direction, making it easy for stakeholders to follow the flow of tasks and decision points. Other line types, such as dotted or dashed lines, serve different purposes in BPMN; for instance, dashed lines are often used for message flows between different pools, while dotted lines can represent associations. Therefore, the use of smooth-lined arrows is essential for effectively modeling and interpreting the internal workflows of a process within a single pool.
