In Salesforce Industries (Vlocity) project methodology, an optimal quote-to-order implementation requires parallel workstreams, especially when designing multi-channel digital experiences that rely on backend APIs such as inventory reservation or device allocation. Public Salesforce implementation practices emphasize that UX design should begin early and only needs high-level API contracts, not full backend development, to progress. This is because modern telecom journeys—product selection, service configuration, device reservation, and inventory validation—depend on microservices exposed through TMF-style APIs or custom integration layers.
Salesforce recommends decomposing work into parallel user stories to accelerate time to market:
UX Design → Driven by user flows, wireframes, and component behavior
Device Reservation API → Defines the interface and payload shapes
Inventory System Integration → Implements backend orchestration
This approach enables the UX team to build using mocked or stubbed APIs, ensuring that design decisions aren’t delayed while backend services are still being implemented. This directly aligns with option D, which reflects Salesforce’s agile implementation strategy.
Options A and B incorrectly assume UX must wait for full integration design, which slows delivery. Option C suggests sequential workstreams, which Salesforce explicitly discourages due to increased cycle time.
Thus, D is the best match.
