User-centered-design in agile RE through an On-site User Experience Consultant

This paper is about experiences with user-centered design (UCD) and agile requirements engineering (RE) in fixed-price projects. Efficiently incorporating usability and UCD into RE remains a challenge. In this paper we describe our experience with the introduction of a team role called `On-site User Experience Consultant' which supports integrating UCD activities tightly in agile RE. We name UCD activities and how they fit in our industrial projects. Also, we describe how old habits in communication and interaction have to change to establish UCD within the project team and with the clients.
