How can I improve the usability of my Web site?
Chris Jasek of Elsevier’s User Centered Design Group answers your usability questions
There are so many facets to usability that it is important to have a framework for assessing usability of a Web site. This aids prioritization of improvements and gives an indication of where to start. We use a technique called heuristic evaluation to identify positive and negative factors influencing usability of a Web site.
We look at these factors under the following headings:
- Consistency
- Orientation and Navigation
- Hypertext and Linking
Page Layout- Aesthetics and Graphics
- Flexibility and Efficiency of Use
- Match Between System and User Activities
- Accessibility
Since 2003, we’ve conducted usability reviews of several academic library Web sites. Our library customers have let us know these usability reviews deliver real value. Given their appreciation and the fact that we can only provide a small number of in-depth reviews per year, we have put together a new Library Connect practical-assistance pamphlet, “How to Design Library Web Sites to Maximize Usability,” to take a closer look at the process we use and to help you become your own usability expert.
