# RC-2 — Operational Validation & Wedding Day Simulation ## Role You are acting as an Independent Wedding Operations Director, Senior QA Lead, and Release Manager. This is NOT an architecture review. This is NOT a code review. Architecture has already been frozen. RC-1 has already been closed. Assume the system will be used by a real paying Couple tomorrow morning. Your responsibility is to determine whether the entire operational workflow is reliable enough for an actual wedding. Think like someone responsible for making sure the wedding day runs smoothly. --- # Current Status Architecture ✅ Frozen RC-1 ✅ Closed No architectural redesigns are allowed. Do NOT recommend: - changing routing - changing guest identity - changing renderer - changing URL strategy Only evaluate operational readiness. --- # Simulation Scenario Assume the following event. Wedding - 500 invited guests Timeline 08:00 Crew arrives 09:00 Guest check-in begins 10:00 Ceremony 11:30 Reception 12:00 Peak arrival 250 guests arrive within 30 minutes Throughout the event Guests - open invitation - RSVP - open maps - play music - submit wishes Crew - search guest - scan QR - manual check-in - correct attendance - verify invitations Couple - monitor dashboard - verify attendance - monitor wishes Administrator - monitor logs - monitor server - handle incidents --- # Part 1 — End-to-End Workflow Validation Audit every workflow. Examples Workspace Creation ↓ Invitation Builder ↓ Media Upload ↓ Publish ↓ Guest Import ↓ Messaging ↓ Guest Opens Invitation ↓ RSVP ↓ Wish ↓ QR Download ↓ Wedding Check-in ↓ Attendance ↓ Reports Determine whether every workflow is complete. Identify broken transitions. --- # Part 2 — Wedding Day Operations Review the actual wedding workflow. Crew Guest Search QR Scan Manual Check-in Walk-in Guest Duplicate Guest Guest without QR Guest forgot phone Guest on wrong invitation Determine whether operations remain smooth. --- # Part 3 — Failure Simulation Simulate realistic failures. Examples Internet unstable Slow network QR unreadable Guest deleted accidentally Guest duplicated Music missing Image missing Server restart Browser refresh Expired session CSRF failure Database reconnect Determine how the system behaves. Can the wedding continue? --- # Part 4 — High Concurrency Simulation Assume 250 guests simultaneously Open invitation RSVP Leave wishes Open gallery Play music Crew scans QR Dashboard refreshes Review Database Renderer Session Caching Locking Concurrency Identify operational bottlenecks. --- # Part 5 — Human Factors Review usability. Couple Crew Guests Ask: Can a non-technical user operate this system? Is every critical action obvious? Can mistakes be corrected? Can operators recover from errors? --- # Part 6 — Wedding Day Checklist Create an operational checklist. Example Before Wedding Database backup Server health Invitation published Guest imported QR downloaded Crew trained Browser tested Printer tested Internet tested Power backup Wedding Morning Dashboard checked Guest list verified QR scanner tested Tablet charged Crew login verified During Wedding Attendance monitored Error log monitored Manual override available Support contact ready After Wedding Attendance exported Guest wishes archived Logs reviewed Backup verified --- # Part 7 — Incident Response Review readiness for incidents. Examples Server down Internet down QR scanner broken Operator mistake Duplicate attendance Accidental deletion Slow response Determine: Detection Recovery Fallback Business impact --- # Part 8 — Release Confidence Score Score: Architecture Operations UX Security Performance Reliability Recovery Maintainability Overall Use a score out of 10. Explain each score. --- # Part 9 — Production Go / No-Go Choose exactly one. --- ## ✅ GO The system is operationally ready. Suitable for Version 1.0 production release. --- ## ⚠ GO WITH RECOMMENDATIONS No blockers. List operational improvements that can be implemented after launch. Do NOT delay Version 1.0. --- ## ❌ NO-GO Identify critical operational failures. Explain why Version 1.0 should NOT be released. --- # Constraints Do NOT redesign architecture. Do NOT recommend Version 2 features. Do NOT invent new modules. Review only: - operational readiness - production robustness - human workflow - recovery capability - wedding-day reliability Judge this system as if a real Couple is depending on it tomorrow morning. Your final decision should be based on operational excellence, not architectural preference.
