Design validation shall include software validation and risk analysis, where appropriate validation shall be completed prior to the delivery or implementation of the product. Records of the results of validation and any necessary actions shall be maintained. As part of design and development validation, the manufacturer shall perform clinical evaluations and/or evaluation of performance of the medical device or in vitro diagnostic medical devices.
