This document outlines instructions for a usability testing workshop. It instructs groups of 3 to 5 members to assess the usability of a web application by considering its purpose, content, navigation, and user inputs. The groups are asked to test a social networking, e-government, or e-learning website and provide a report with the website details, testing strategy, results, and recommendations. The report should also include a reflection on the assessment process. The document recommends using both performance and satisfaction metrics for a valid face-to-face or online usability test. It also provides resources for usability testing tools.
