Use case Diagram Components: This is how a use case diagram looks.
What was found was that the use case diagrams conveyed the intent of the system in a more simplified manner to stakeholders and that they were "interpreted more completely than class diagrams". Before we get into the steps of building use cases I wanted to break down the components of a Use Case diagram as well as that of a use case. Siau and Lee conducted research to determine if there was a valid situation for use case diagrams at all or if they were unnecessary. 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. This diagram consists of actors, use cases and relationships between them. It has been said before that "Use case diagrams are the blueprints for your system". The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development.
