Accenture utilizes a technique described as "low-fidelity prototyping" when designing user interfaces. This method has designers and users design screens together using paper template items. Hence, if the user indicates that another item should be added to the screen, such as a button, the designer picks up a paper object shaped like a button and allows the user to place it on the paper designated as the screen. Compare and contrast the advantages and disadvantages of using low-fidelity prototyping in the design of a DSS to those associated with using "high-fidelity prototyping" of designing screens with a product on the computer.
