Develop Use Case Diagram Task

The ideal source for the system use case model is a business model. If this is available, then system actors and system use cases can be explicitly mapped from business actors, business workers, primitive business processes and business worker responsibilities.

Otherwise system actors and use cases will have to be found directly from a stakeholders understanding of the system requirements. This would normally be done in a workshop with the stakeholder.

The diagram cannot be fully structured until the detail of the use case flow has been developed, so don't spend a lot of time developing the diagram before developing the use case document.
