Abstract

In this article we present a comparative study of three methods: Cognitive Walkthrough, Heuristic Evaluation, and Communicability Evaluation. The aim of the study is to compare costs and benefits of the three, so as to inform decisions about which one to choose when time and feedback for (re)design are the most critical factors. The study was carried out as an academic exercise by graduate students in HCI. Results suggest that, of the three methods, Communicability Evaluation produces the most informative results, whereas Heuristic Evaluation is the most cost-effective.
