User Feedback in Mobile Development

Abstract

Developers need to obtain feedback early to build applications that fit to the users needs. In this paper we show how the combination of two approaches enables developers to continuously improve usability and user experience of mobile applications. The Tornado model is a light-weight scenario-based approach for producing executable prototypes. Rugby, an agile process model based on Scrum, allows the developer to continuously deliver these prototypes at any time during a sprint to obtain feedback.
