Design Verification is a required quality control process in medical device manufacturing that ensures a product is built correctly according to its design specifications. It's like a thorough checklist system that confirms all the requirements set during the design phase are met in the final product. This process is essential because medical devices directly impact patient safety. Companies must do this to comply with FDA regulations and similar rules in other countries. You might also see it called "DV," "Design V&V" (Verification and Validation), or "Product Verification."
