Usability is one of several quality aspects (also named non-functional requirements) according to ISO 9126. The elicitation of those during an early phase of the development is crucial in information systems as well as in embedded systems. Despite the practical importance of usability and additional aspects like performance and maintainability, and so forth, there is rarely any guidance on the elicitation of these requirements. We present an approach to elicit usability requirements in concert with supplementary requirements based on a use case based specification of functional behavior.
