Assessment of Usability Benchmarks: Combining Standardized Scales with Specific Questions
The usability of Web sites and online services is of rising importance. When creating a completely new Web site, qualitative data are adequate for identifying the most usability problems. However, changes of an existing Web site should be evaluated by a quantitative benchmarking process. The proposed paper describes the creation of a questionnaire that allows a quantitative usability benchmarking, i.e. a direct comparison of the different versions of a Web site and an orientation on general standards of usability. The questionnaire is also open for qualitative data. The methodology will be explained by the digital library services of the ZBW.
