It allows visualizing the system structure and possible users interactions that would need to be considered for its application.

What is a Use Case Diagram?

A use case diagram is a visual representation employed in software engineering to depict the functional requirements of a system, emphasizing the interactions between the system and its external entities, typically users or other systems.

These diagrams are part of the Unified Modeling Language (UML) and serve as a tool for capturing the user's perspective of system behavior. They consist of actors (users or other systems), use cases (activities or processes that the system performs), and the relationships between them.

Use case diagrams are particularly valuable in understanding and communicating how a system is intended to interact with its environment, aiding in clarifying requirements, identifying system scope, and providing a high-level overview of system functionality. The focus is on the system's environment and the user's perspective, ensuring a user-centric focus for better contextual coverage.
