In a business process model, actors are represented by?

In a business process model, actors are represented by lanes. Lanes are used in diagrams such as Swimlane diagrams to distinguish different actors or organizational roles that participate in a process. Each lane visually separates the activities and responsibilities of different actors, allowing for a clearer understanding of who is responsible for what within the process. This structure is essential in illustrating the interactions and flow of work among various roles and ensures clarity in the representation of the overall process.

While roles, shapes, and nodes relate to different aspects of modeling, they do not specifically denote the actors in the way that lanes do. Roles might define the responsibilities, but they don’t provide the visual separation needed to demarcate different actors in a process model. Shapes and nodes may represent tasks or decision points but do not serve to distinguish the participating actors as effectively as lanes do.
