Adding usability: A case study

This paper describes a case study that has been performed at the Medical Products Agency (MPA) which is the authority responsible for the whole process of drug approval and control in Sweden. The purpose with this case study was to apply a new approach to user interface design in the development of an information system for employees at the MPA. Analysis of Information Utilisation was used in conjunction with User Interface Modelling to gather and specify requirements relevant for the design of the user interface. The design was performed in an iterative process where the style and the content of the interface was evaluated during each iteration. The work was divided into two phases. Phase one included analysis of user require-ments and design of a first version of a prototype. In the second phase the iterative process of design was studied. The methods used in the two phases were evaluated and the results show that this approach to design increases the possibilities to create interfaces with higher usability. 1
