Producing prototypes is one of the most essential parts of any product development. It can be important for the highly technical sphere of product design as well as the most basic of product design. It allows everyone involved a clearer idea of the functionality of the product, and the first real opportunity to test the thing for areas to improve upon.
Prototypes often are produced multiple times in multiple forms before everyone is satisfied that the product is ready for launch. Depending upon how the process has been undertaken, the first prototype could be something that is all about the functionality of the thing. At this stage, you’ll be able to discover relatively easily if the product actually serves a practical purpose, but it certainly isn’t ready for launch. You’ll still need to refine the design so that it takes account of how easy it is to use as well as its appearance.
