Working at the dental implant company, I have been exposed to the design control that have been mentioned in the lecture. During the beginning of the project, the general purpose of the medical device or its function is established. This is defined as the user needs which are communicated by the marketing team. After that design and development stages & activities are identified. The responsibilities and the appropriate resources are defined during this stage too. Design reviews take place when the user needs are drafted and design input are established. Design validation and verification are also carried out during the product development. Finally the design transfer is initiated and completed.
