There can never be an exhaustive list of prototyping methods, since there is quite literally an endless number of ways you can build prototypes. What we can do, however, is provide a useful list of the eight most common prototyping methods, together with best practice tips that help you maximise your prototyping and testing sessions. By arming yourself with these eight common methods, you can begin your iterative process of building prototypes in order to empathise with your users, to decide on and refine your ideas and to test your solutions.
