Paper prototyping is a quick and cost-effective method to test the possible range of features and the order of selected interaction elements within a product. By means of paper prototyping concepts, workflows, layouts and features can be visualized. With that the features mentioned in use cases and user scenarios are initially collected and subsequently sketched and arranged to an interface. This way it is made sure that all requirements are met by the interface.
Paper prototypes are created quickly and resource efficient. This way they can be validated very early in the product development process so that possible mistakes can quickly be recognized and corrected by minimal effort. As the interfaces are sketched quite roughly, the user’s feedback focuses on the basic functionality rather than the graphical design.
