Most of the example above described some variation of testing as their chief form of design verification. But verification is more than this, it is making sure that the design of the device is right, i.e. it meets its required technical standards. For this, the workmanship of the product must also be scrutinized with inspections and design reviews.

Design validation, on the other hand, should test whether the right device was produced; meaning that the suture you created actually and properly closes wounds. This is why design validations for medical devices are usually accompanied with clinical trails and human factors studies.

I also touched upon this in an earlier post ” Discussion Topic: To trial or not to trial.”
