Description: Detailed design review activities are an activity within the ITS system engineering process and provide opportunities for system refinement, upgrades, and improved integration.

Keywords: Transportation, tolling, ITS, intelligent transportation system, system engineering, system integration, design review, requirements review, cap ex, op ex, testing, review, schedule, scalability.

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.

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.
