I believe that in a project’s life cycle, all subsections are essential when it comes to a product’s development. When it comes to medical device development, the cycle is broken down into numerous of phases such as concept design (user needs), design planning (design input) , product design (design process), design verification (design output), design validation (finished device), design transfer and everything is connected with design review. These phases and controls hold an important role in the project’s life cycle, this is the general project process cycle that the FDA uses as a guideline for medical device companies. As an engineer, the wheel doesn’t need to be reinvented but instead to build upon the current technology and fix problems that user encounter currently while introducing innovative solutions. There aren’t a least important phase because even the initial phase being the concept design, the user needs is what fuels the project and initiates the idea on what the user (costumer) is asking for, without this, the product will have no substance. The design review I believe could be a crucial part of the cycle since this helps the team to inspect all aspects of the phases and even beyond the completion of the product.
