CASE ANALYSIS
Scenario
A B2B wholesale platform uses this diagram to detail buyer interactions, enabling bulk ordering with integrated inventory checks and payment processing, while supporting optional price negotiation before order commitment.
Key decisions
- Included Check Inventory and Process Payment as mandatory sub‑use cases of Place Order using includes.
- Used an extension for Request Quote to handle optional bulk discount negotiation prior to final order.
- Modeled Payment Gateway and Inventory System as external system actors to clarify system boundaries.
When to reuse this
Applies to any B2B e‑commerce system where buyers browse catalogs, place bulk orders, optionally request quotes, and rely on external services for payment and inventory validation.
