Chattratichart, Jarinee and Lindgaard, Gitte (2008): A comparative evaluation of heuristic-based usability inspection methods. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2213-2220. Available online

“Given that heuristic evaluation (HE) is a popular evaluation method among practitioners despite criticisms surrounding its performance and reliability, there is a need to improve the method's performance. Several studies have shown HE-Plus, an emerging variant of HE, to outperform HE in both effectiveness and reliability. HE-Plus uses the same set of heuristics as HE; the only difference between these two methods is the 'usability problems profile' element in HE-Plus. This paper reports our attempt to verify the original profile employed in HE-Plus based on usability problem classification in the User Action Framework and an experiment evaluating its outcome by comparing HE with two HE variants using a profile (HE-Plus and HE++) and a control group. Our results confirmed the role of the 'usability problems profiles' on improving the performance and reliability of heuristic evaluation: both HE-Plus and HE++ outperformed HE in terms of effectiveness as well as reliability.”

Lindgaard, Gitte and Chattratichart, Jarinee (2007): Usability testing: what have we overlooked?. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 1415-1424. Available online

“For more than a decade, the number of usability test participants has been a major theme of debate among usability practitioners and researchers keen to improve usability test performance. This paper provides evidence suggesting that the focus be shifted to task coverage instead. Our data analysis of nine commercial usability test teams participating in the CUE-4 study revealed no significant correlation between the percentage of problems found or of new problems and number of test users, but correlations of both variables and number of user tasks used by each usability team were significant. The role of participant recruitment on usability test performance and future research directions are discussed.”
