The Business Use Case Model is a simple diagram (using UML notation) identifying business actors and their goals for interacting with the business. The Business Use Case Model identifies the Artifact: Business Use Cases that define business processes and how the business serves its customers. The model aids in establishing the context of the business.
The Business Use Case Model represents the scope of a business. The Artifact: Use Case Model represents the scope of an application. Therefore, a single Business Use Case Model may have many (system) Use Case Models associated with it, where each Use Case Model represents a single application.
The following roles use the Business Use Case Model:
- The Role: Business Process Analyst and Role: Business Designer use it to define and improve business processes and align organizational design to serve customers' needs.
- The Role: Requirements Analyst uses the model as an input to defining application requirements including actors, use cases, use case relationships, and Artifact: Supplementary Specification.
- The Role: Stakeholder uses it to verify that the project team understands the business and project scope.
- All other roles may use the Business Use Case Model to understand the business and the value it provides.
