Abstract: When we added heuristic evaluation to our expert analysis method, we found that it worked well in our interdisciplinary environment, but that its recommended prioritization strategy (which ranks problems according to severity) has some 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 that 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.
