Student thesis: Bachelor


There is a lot of research on design guidelines to increase the usability of secure IT systems and that problems with usability can cause problems in IT systems. However, research on the actual consequences that can arise from how usability has been implemented in secure IT systems is limited. The purpose of the study is to fill this gap of knowledge and the study was conducted as a case study based on qualitative interviews with seven participants. The participants were interviewed about their use of the IT system PRIO, their responses were then analyzed to find themes. These themes were used as a basis when we worked through the results. We found that PRIO has a lack of usability and found consequences because of this: lack of information and lack of simplicity in the IT system leading to handling errors, poor performance leading to long start-up times which in turn leads to security risks due to the human factor, and that operational disruptions leads to the IT system not being able to be used.
