CASE ANALYSIS
Scenario
An online platform connecting customers with experts for consultation sessions, including payment and rating features.
Key decisions
- Chose to model 'Make Payment' as included in 'Request Consultation' and 'Rate Expert' as extending it upon session completion.
- Introduced 'Validate Payment' as an included sub-use case to connect to the external payment gateway.
- Kept actors distinct: Customer initiates most use cases, Expert reviews requests, and Payment Gateway external.
When to reuse this
When modeling a service marketplace with user roles, external payment systems, and conditional extension (e.g., rating after session).
