The Role of Verification, Validation, and Safety in product verification and validation Design Reviews
Product development is more than just having a great idea—it requires meticulous planning, testing, and evaluation. Product design reviews, verification and validation (V\&V), and safety assessments are critical components of this process. These steps ensure that the product performs as expected, meets user needs, and adheres to safety and regulatory standards.
Product Design Review: The First Line of Defense
A product design review is a formal meeting where engineers, designers, quality experts, and safety professionals evaluate the product’s design specifications. The objective is to ensure the design is technically sound, cost-effective, and aligned with customer requirements. This review typically includes an assessment of materials, mechanical and electrical schematics, and performance expectations.
Verification and Validation: Building the Right Product Right
Verification answers the question: Did we build the product right? It ensures that the product was developed according to the design specifications. Verification activities include prototype testing, code reviews (in software), and engineering simulations.
Validation answers: Did we build the right product? This ensures the final product meets user expectations and performs in real-world conditions. Validation includes field testing, usability studies, and customer feedback analysis.
When both are properly executed, they drastically reduce the risk of product failure and increase customer satisfaction.
Product Safety Review: Minimizing Risks
A product safety review focuses on identifying any risks the product may pose during use. It examines:
Hazardous materials
Mechanical or electrical failures
Compliance with safety regulations like ISO 12100, IEC 60601, or UL standards
The goal is to design out risks where possible and implement controls or warnings where risks can’t be eliminated entirely.
Quality Verification and Validation
Quality V\&V ensures the final product not only works but also maintains high standards throughout its lifecycle. This includes:
Inspection of finished goods
Stress and fatigue testing
Reliability analysis
- Compliance with quality standards (ISO 9001, Six Sigma)
Combining all of these reviews in a structured format—such as a design review tree—enables continuous feedback and improvement. This proactive approach prevents late-stage failures, shortens time-to-market, and ensures customer satisfaction.
Conclusion
Every successful product undergoes rigorous design reviews, verification and validation, and safety assessments. These processes form the backbone of high-quality, reliable, and safe products. Companies that invest in structured product evaluation processes ultimately save money, protect users, and enhance their market reputation.
