As the next step in producing an improved website for Moffett, students develop an HTML mock-up of the new website. They then perform a heuristic analysis on the site designs of other students teams, based on usability factors such as ease of use, look and feel, and navigation. Finally, students modify their mock-up HTML code to incorporate feedback from others on their initial design. Once each team revises their site designs following the heuristic analyses, students user-test their interfaces with prospective users and report their findings and proposed changes.
