Risk Mitigation​

Risk: Real-time chat complexity​

Mitigation: Start WebSocket integration early (Sprint 3). Have REST fallback ready.

Mitigation: Test early and often. Have in-app polling fallback.

Risk: App Store approval delays​

Mitigation: Submit 1 week before launch. Have rejection response plan.

Risk: Seller supply low​

Mitigation: Pre-recruit 20-30 sellers before launch. Fast approval process.

Risk: Infrastructure costs exceed budget​

Mitigation: Start with minimal AWS setup. Scale as needed. Monitor costs daily.
