Representations

tool description

The use cases are traditionally used in the interaction design projects for the development of the interaction flows. They are a means of roughing out the functionality of a product or of a service. Developers are very accustomed to seeing them and will understand them immediately, as will the business people who have over the years had to use them to communicate with programmers.
