Who would be modeled in the top lane of a business process model?

In a business process model, the top lane is typically designated for the triggering actor, which plays a crucial role in initiating the business process. The triggering actor represents the individual, group, or system responsible for starting the process, effectively setting it in motion. This positioning is essential because it clarifies where the process begins and establishes accountability for the actions that follow.

By focusing on the triggering actor, the model highlights the dynamic interaction between the actor and the process, providing insights into the relationship between parties involved. This can help stakeholders understand who is responsible for what actions and how the process responds to external inputs. In this way, the top lane serves as the key entry point for understanding the context of the business process, making it vital for effective modeling and analysis.
