I came away from a DevCSI workshop: paper-based agile design techniques beaming with ideas. The workshop provided a useful introduction to agile methodologies and card-based techniques. Agile techniques are relevant to UX2's development of library systems and user interfaces, which are mainly working prototypes for evaluation purposes. Adopting an agile method seems logical. In a previous post, I described the work on an open source library user interface. The prototype has since been evaluated through a usability test involving a group of users from the University of Edinburgh. This post discusses the agile method introduced at the DevCSI workshop as a plausible development framework for UX2's UI development following the usability test.
