  • Heuristic evaluation : Comparing ways of finding and reporting usability problems
  • 2007

    • Research on heuristic evaluation in recent years has focused on improving its effectiveness and efficiency with respect to user testing. The aim of this paper is to refine a research agenda for comparing and contrasting evaluation methods. To reach this goal, a framework is presented to evaluate the effectiveness of different types of support for structured usability problem reporting. This paper reports on an empirical study of this framework that compares two sets of heuristics, Nielsen's heuristics and the cognitive principles of Gerhardt-Powals, and. two media of reporting a usability problem, i.e. either using a web tool or paper. The study found that there were no significant differences between any of the four groups in effectiveness, efficiency and inter-evaluator reliability. A more significant contribution of this research is that the framework used for the experiments proved successful and should be reusable by other researchers because of its thorough structure.

  • Aligning quality assurance at the course unit and educational program levels
  • 2016

    • Quality assurance is a subject that has grown dramatically in importance in recent times. In previous work, we have described how the ACM Curricula can be used to support the Quality Assurance process of educational programs, using the Computer Science program at Reykjavik University as an example. Faculty members and employers of graduates participated in the process, that resulted in providing both detailed quantitative data and qualitative information. The assessment also raised awareness of how abstract topics and learning outcomes from an international standard can be used when revising the curricula of a particular course in a CS program. Quality assurance is indeed a continuous process, where the results of evaluations should be used to drive improvements. In this paper we focus on how a Database course was re-structured based on a recent quality assurance process.

  • Listen to your users : The effect of usability evaluation on software development practice
  • 2009
  • Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • A vast majority of the people in the western world use software systems on daily basis for achieving their goals. To be able to do that each person needs to communicate what he or she wants to do to the system and receive a response. This communication needs to be easy for the user, especially when the system is new to him or her. Otherwise, the user either quits using the system; it takes a very long time or gets very irritated. A software team that is making new software needs to evaluate the usability of the system and various methods have been introduced in the literature to do that.My research focus in this thesis is on usability evaluation. I study particularly, how usability evaluation methods can be compared, what data should be gathered in usability evaluation to gain knowledge on how the software affects users who are getting new software for their daily work and how useful this data is to the recipients.Two experiments are reported in this thesis where results from using three different usability evaluation methods are compared. The main result from these two studies is that the think-aloud evaluation method should be used, if the goal of the evaluation is to gather as realistic information as possible on usability problems that the users will have when using the system.Furthermore four case studies are described in the thesis, in which usability evaluation was done by using the think-aloud method in co-operation with real users in their real work situation. These studies give much richer information on the actual use of the systems involved.The findings from one of these case studies indicate that the results from user observation done on a system that users have not seen before or used only for few days are rather similar to the results from usability evaluation done when users have used the system for a longer period. So the common practice of doing user observation on a software system that the participants have not seen before and then interpreting that the results will be the same for actual usage of the system when users will use the system for their real tasks for shorter or longer period is adequate.
