Risk Assessment

High Risk Areas: None

All critical requirements have complete traceability.

Medium Risk Areas: 2

1. Performance Validation (Req-NFR-1)

   • Risk: 1000 concurrent endpoints may exceed memory limits
   • Mitigation: PerformanceScalabilityTest with memory profiling
   • Status: Designed, pending implementation

2. Thread Safety (Req-Arch-8)

   • Risk: Concurrent access to DataBuffer
   • Mitigation: ConcurrentLinkedQueue + comprehensive concurrency tests
   • Status: Designed, pending implementation

Low Risk Areas: 4

1. Build Configuration (Req-Arch-1, Req-NFR-5)

   • Risk: Manual validation required
   • Mitigation: CI/CD enforcement

2. Normative Compliance (Req-Norm-1, Req-Norm-2, Req-Norm-5)

   • Risk: Process-based, not automated
   • Mitigation: Scheduled audits and reviews

Conclusion

The HSP project demonstrates excellent requirements traceability with:

• 100% architecture mapping: All requirements mapped to components
• 100% implementation mapping: All requirements mapped to Java classes
• 94.6% test mapping: Nearly all requirements have automated tests
• No orphan requirements: Every requirement justified and traceable
• No critical gaps: All functional requirements covered

Minor gaps (build validation and process compliance) are low-risk and addressable through CI/CD pipelines and scheduled audits.

Recommendation: Proceed with implementation following the TDD approach outlined in the SPARC methodology.
