Follow-Up Links
Section titled “Follow-Up Links”Board Insights & Common Pitfalls
Section titled “Board Insights & Common Pitfalls”Generalized Judge Questions
Section titled “Generalized Judge Questions”- Ride History LDV: “You have millions of ‘Customer Ride’ records. How will you prevent performance degradation on the mobile app when a user views their history?”
- Media Storage: “Why did you choose AWS S3/Azure Blob for ride photos and videos? How do you link these back to Salesforce without hitting the 2GB file limit?”
- Queue Accuracy: “How do you ensure ‘Estimated Queue Time’ is accurate in real-time across all parks? What happens if the integration with the ride sensors fails?”
- Mobile Signal Dead-Zones: “Steel-framed roller coaster buildings are often data dead-zones. How will your app handle QR code check-ins and health waiver signing offline?”
- Privacy Compliance: “How are you protecting sensitive health self-risk acknowledgments? How do you handle ‘Right to be Forgotten’ for customers with years of ride history?”
Common Mistakes
Section titled “Common Mistakes”- Ignoring Offline Waivers: Not accounting for the “Dead-Zone” requirement. Health waivers and QR scans must be handleable via offline priming or local caching.
- Over-Engineering Queue Logic: Calculating complex ride queue times entirely within Apex instead of offloading to an external system or using a simple average.
- Neglecting Safety Escalations: Missing a clear “Emergency Escalation” process for health issues detected at the ride entrance (e.g., using Omni-Channel for first-aid specialists).
- License Over-licensing: Assigning expensive Sales Cloud licenses to park specialists who only need to update ride statuses or view cases.
Strong Patterns
Section titled “Strong Patterns”- External Media Links: Storing high-volume ride photos/videos in external storage (S3) and surfacing them in the mobile app via custom URLs or External Objects.
- Field Service for Maintenance: Using Salesforce Field Service (FSL) for the engineers fixing the rides, using native scheduling and offline work orders.
- Social ID for Frictionless Entry: Using Social Sign-On (Google/Facebook) for park guests to reduce friction during app onboarding.
Strategic Insights
Section titled “Strategic Insights”- The “High-Concurrency” Test: URC probes the architect’s ability to handle massive spikes in mobile traffic (e.g., when a park opens) and high-volume media storage.
- Safety-First Thinking: Success depends on demonstrating a “Safety-Critical” architecture where maintenance and health waivers are hard gates.
Additional Notes
Section titled “Additional Notes”- Global theme park scenario focusing on guest experience, ride maintenance, and high-volume media data.
- Heavy emphasis on mobile strategy and safety-critical integrations.
