CASE ANALYSIS
Scenario
An event planner uses the PlanIt Go system to create events, manage budgets, integrate external vendors, and process payments.
Key decisions
- Modeled Vendor and PaymentGateway as external system actors (rectangles).
- Vendor integration is broken into main use case with include (Connect API) and extend (Test Integration).
- Budget management always includes payment processing, so modeled as «include».
When to reuse this
Applicable for any event management or vendor marketplace system requiring clear role interactions and system boundaries.
