Comparative usability evaluation (CUE-4)

Testing the Unknown – Value of Usability Testing for Complex Professional Systems Development

“…The problem-centric approach of usability testing, the validity and the reliability of found problems as well as the value of succeeding design recommendations are all questioned in the past [6,7,8,9,10]. Major challenges have been that most of the reported usability problems only confirm earlier impressions of developers [11] i.e.…”

“…Major challenges have been that most of the reported usability problems only confirm earlier impressions of developers [11] i.e. developers are not very interested in usability problems, nor do they react on these [9].…”

Active and passive physicality: making the most of low fidelity physical interactive prototypes

“…Users were asked to complete six tasks and the success rate of each task was recorded (Molich & Dumas, 2008) along with the time taken to complete the task. The 'high fidelity' prototype produced similar results to the final device, significantly outperforming the 'software-only' prototype.…”

Exploring Multiple Usability Perspectives

“…This problem is in the literature described as lack of designchange effectiveness [4], lack of downstream utility [2], or lack of impact [1], and can partly be explained by lack of persuasive power [4] in the usability feedback. Recent studies show that a large number of usability issues are known to stakeholders prior to usability evaluations are conducted [1,3,5], and this suggests that feedback given to stakeholders are not adequate. In this paper we suggest an approach to explore and possibly increase adequacy and persuasiveness of feedback from usability work.…”
