The drawings attempt to mimic the real world and provide a view for the stakeholder to understand how the system is going to be designed.
ĭue to their simplistic nature, use case diagrams can be a good communication tool for stakeholders. It has been said before that 'Use case diagrams are the blueprints for your system'. While a use case itself might drill into a lot of detail about every possibility, a use-case diagram can help provide a higher-level view of the system. The actors are often shown as stick figures. The use cases are represented by either circles or ellipses. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well.
A use case diagram is a graphical depiction of a user's possible interactions with a system.
