Consequences of lack of usability in a secure IT system (English)
Abstract [sv]

Det finns mycket forskning om designriktlinjer för att öka användbarheten i säkra it-system samt att problem med användbarheten kan ge problem i it-system. Men forskningen om vilka faktiska konsekvenser som kan uppstå av hur användbarhet implementerats i säkra it-system, är begränsad. Syftet med studien är att fylla denna kunskapslucka och genomfördes som en fallstudie som baserar sig på kvalitativa intervjuer med sju deltagare. Deltagarna intervjuades gällande deras användning av it-systemet PRIO, deras svar analyserades sedan för att hitta teman. Dessa teman användes som grund när vi arbetade genom resultatet. Vi hittade att PRIO har bristande användbarhet och hittade konsekvenser på grund av detta: brist på information och brist på enkelhet i it-systemet som leder till handhavandefel, dålig prestanda som leder till långa uppstartstider som i sin tur leder till säkerhetsrisker tack vare den mänskliga faktorn, samt att driftstörningar leder till att it-systemet inte går att använda.

Abstract [en]

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.
