Q&A (10 min) 7. **Decision**: Approve budget and proceed? **Benefits of this approach:** - ✅ Not overwhelming (bite-sized information) - ✅ Allows for questions and feedback - ✅ Separates business and technical concerns - ✅ Builds momentum and consensus --- ## 📋 Pre-Meeting Checklist ### For Madhu (Before Presenting): - [ ] Review ONE_PAGE_SUMMARY.md thoroughly - [ ] Walk through EXECUTIVE_PRESENTATION.md - [ ] Understand DATABASE_ERD.md at high level - [ ] Prepare answers to expected questions - [ ] Identify key decision makers - [ ] Set meeting objectives clearly - [ ] Have backup plans for concerns ### For Stakeholders (To Request): - [ ] Read ONE_PAGE_SUMMARY.md before meeting - [ ] Come prepared with questions - [ ] Identify budget availability - [ ] Determine timeline constraints - [ ] Consider resource availability - [ ] Think about bank prioritization --- ## 📊 Expected Stakeholder Questions & Answers ### Business Questions **Q1: Why ₹80L investment?** **A**: Development (₹40L), Infrastructure (₹5L), Testing (₹8L), Training (₹5L), PM (₹6L), Support (₹3L), Contingency (₹10L), Others (₹3L). ROI is 19% Year 1, 378% Year 2, 445% Year 3. Payback in 12-14 months. **Q2: Why 20-24 weeks? Can we go faster?** **A**: This is aggressive timeline with MVP approach. Phases are: MVP (8-10w), Docs/Review (4-6w), Reports/Admin (4-6w), Mobile (3-4w). We can compress but risk quality. Alternative: Launch MVP in 10 weeks, then iterate. **Q3: What if banks don't adopt?** **A**: Pilot with 1 bank first (HDFC or SBI), prove value, then expand. Bank-specific customization built into design. We can clone their workflow exactly, just digitize it. **Q4: Can we handle existing workload during transition?** **A**: Yes. Parallel run for 2 weeks. Old system stays active during transition. Gradual migration, not big bang. ### Technical Questions **Q5: Why React and not Angular/Vue?** **A**: React has largest ecosystem, best mobile support (PWA), most developers available, and aligns with modern web standards. Flexible and performant. **Q6: Why PostgreSQL and not MongoDB?** **A**: Relational data (valuations, properties, users) fits SQL better. PostGIS extension for maps. ACID transactions for financial data. Better for reporting queries. **Q7: What about Google Maps cost?** **A**: Free tier: 28,000 map loads/month. With 10,000 valuations/year (833/month), well within limit. If exceeded, ~₹2/load beyond free tier. Estimated max ₹50k/year. Can switch to Mapbox if needed. **Q8: How secure is the system?** **A**: JWT authentication, role-based access, encrypted data (transit & rest), audit logging, session management, 2FA optional, HTTPS only, IP whitelisting option. ### Timeline Questions **Q9: When can we start pilot?** **A**: If approved today, pilot can start in Month 3 (Week 12). MVP development takes 8-10 weeks, then 2 weeks testing/stabilization. **Q10: When can we decommission old system?** **A**: Month 6-7 after all teams trained, data migrated, and 2-week parallel run completed successfully. --- ## 🚀 Next Steps (If Approved) ### Week 1-2: Preparation 1.
