ABSTRACT
To take advantage of the interdisciplinary experience of our colleagues, we decided several years ago to add heuristic evaluation to our expert analysis method. Although heuristic evaluation is a cost-effective method for evaluating interfaces, we found that the recommended prioritization strategy--ranking the problems according to severity--has several limitations. Specifically, it does not address how much it will cost the developers to fix the problems, nor does it adequately capture the distinction between high-level (global) and low-level (specific, screen-level) problems. To address these limitations, we developed a method which retains the richness of heuristic evaluation, but communicates the results in such a way that project managers, developers, and designers can form a clear and immediately executable plan for addressing the problems. Our method integrates user research, heuristic evaluation, affinity diagramming, cost-benefit charts, and recommendations into a report that others can use to plan both short and long-term improvements.

Using a new set of heuristics in evaluating Arabic interfaces
AbstractThe Information Technology Sector has been growing rapidly in the Arab world. As a result, Arabic interfaces are now being widely used and developed in the region. However, little existing work has been done that focused on evaluating ...
Usability Heuristics for Transactional Web Sites
ITNG '14: Proceedings of the 2014 11th International Conference on Information Technology: New GenerationsOne of the most recognized methods to evaluate usability in software applications is the heuristic evaluation. In this inspection method, Nielsen's heuristics, are the most widely used evaluation instrument. However, there is evidence in the literature ...
Coming to terms: comparing and combining the results of multiple evaluators performing heuristic evaluation
CHI EA '07: CHI '07 Extended Abstracts on Human Factors in Computing SystemsIn this paper we describe a new way to perform heuristic evaluations, which allows multiple evaluators to easily compare and combine the results of their reviews. This method was developed to provide a single, reliable, result to the client, but it also ...
