## Research Findings

### 1. Microservices Architecture Best Practices

Based on research from industry sources:
- **Non-functional requirements** are critical for microservices architecture
- **Testing** must cover unit, integration, performance, security, and accessibility
- **Infrastructure** requires comprehensive DevOps, monitoring, and disaster recovery
- **Compliance** (GDPR, PCI-DSS, local regulations) must be built-in from the start

### 2. Insurance Platform Specific Requirements

Key findings:
- **Performance testing** is essential for high-volume transaction processing
- **Security testing** must include penetration testing and vulnerability scanning
- **Accessibility** (WCAG 2.1 AA) is required for customer-facing interfaces
- **Disaster recovery** planning and testing are critical for business continuity
- **Compliance testing** must cover multiple regulatory frameworks

### 3. BRD Coverage Best Practices

- Requirements should be traceable to BRD sections
- Non-functional requirements should be explicitly documented
- Testing tasks should reference both functional and non-functional requirements
