The development of professional medical software is often behind the curve in both technical and design implementation. This is in part due to the slow rate of replacement of software within medical institutions. Additionally, users are often not consulted in the development of these types of software. In the case of medical software, this can often have unforeseen and unfortunate consequences. User Experience research shows that involving users at every stage in the development of software leads to improved effectiveness, improved overall usability, and compliance with regulatory standards. By carrying out workshops and surveys, Cirdan has investigated which features have the highest priority for users within the development of Laboratory Information Systems (LIS). The results of this research are having a direct influence on the future of LIS within Cirdan.
