Question

Accepted Answer

Design verification ensures the product is designed correctly, while design validation ensures the correct product is designed.

Design verification confirms that the design output meets the design input requirements.
Design validation confirms that the product meets user needs and intended use.
Verification is done before validation in the design process.
Verification can include activities like reviews, inspections, and testing.
Validation typically involves testing the actual product with end users.
Example: Verifying that a medical device meets all specified requirements is design verification. Validating that the device effectively treats patients is design validation.
