Usability Evaluation of an XP Product

User-centered design (UCD) is a design approach that stresses attention to usability throughout the development process of software. However, with the growing interest in agile development methods, research attention has been focused on some aspects of incompatibility between agile development and the principles of UCD. There is a growing interest in finding a place for usability evaluations and UCD in the agile development framework. This paper presents the findings of an evaluation of an XP prototype using a discount, cooperative usability evaluation approach. The findings indicate that the evaluation setup, with modifications, could be used for iterative usability evaluation during the continuation of the XP project in question.
