CASE ANALYSIS
Scenario
This diagram models the primary use cases of a mobile shopping application, including customer interactions, payment processing, and inventory management.
Key decisions
- Used 'include' for Checkout→Pay and Pay→ValidateCard to show mandatory sub-steps
- Modeled Payment Gateway and Inventory System as external actors
- Kept the diagram simple by omitting extend relationships (e.g., no optional features such as discount codes)
When to reuse this
When designing or documenting a mobile shopping app's functional requirements, showing how actors interact with payment and inventory systems.
