## 📊 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.
