2. Methodology
Rigorous design reviews require a multi-day
review cycle to review each requirement
identified in the requirements traceability
matrix.
Design requirements are validated against
contractual requirements, performance
requirements, industry best practices,
change requests and any new requirements.

8. Methodology
 Ensure sufficient time in the schedule (typically 3 to 5
days) based on project size and complexity.
 Allow time for subsequent change requests and
modifications following design review.
 Ensure all previous documentation and subsequent
documentation reflects any new design changes.
