The automation boundary on a use case diagram delineates the scope of the system being developed, indicating which functionalities will be automated and which will remain manual. It visually separates the automated processes within the system from the external actors that interact with it. This boundary helps stakeholders understand what is included in the system's automation and clarifies the interactions between users and the automated system. It is typically represented as a rectangle that encompasses the use cases while excluding external elements.
The four basic parts of a use case model are actor, use case, system boundary, and relationships between actors and use cases. Actors are users or systems interacting with the system, use cases represent user goals or tasks, the system boundary defines the scope of the system, and relationships show how actors interact with use cases.
