However, it is common to note usability problems that occur during testing, and to interview the participant after the task to obtain an understanding of the problems.Several benefits of using scoring rubrics in performance assessments have been proposed, such as increased consistency of scoring, the possibility to facilitate valid judgment of complex competencies, and promotion of learning.This paper investigates whether evidence for these claims can be found in the research literature. Summative usability testing is used to obtain measures to establish a usability benchmark or to compare results with usability requirements.The usability requirements should be task-based, and should tie directly to product requirements, including results from analytic tools such as personas, scenarios, and task analysis.The effects of this modification on one or several dependent variables are then measured and statistically analyzed.
