ABSTRACT
Design input is probably the most critical element of the design control process. It is the foundation for the entire design and development activity. The output should be sufficient for full-scale models to be made if required and design inputs to be formalized. If management decides to move forward with the design and development of the product, appropriate approval(s) should be documented and a design team, composed of personnel representing different disciplines, should be assembled to initiate the design and development process. The concept document, or Product or Project Initiation Request, is the starting point for the design and development process. It defines the basic requirements for a product that is, or is about to be, developed. The outcome of design and development process can then be reviewed by key company personnel so that a decision can be made as to whether the project should move forward into development.
