S3 Web Technologies scores in Nielsen Norman Group usability study
cont.

The study examined two aspects of Flash animations. The first was "feature success," i.e. the degree to which users could successfully work with the features of the animation, regardless of whether they could complete a given task. The second was "task success," which assessed whether users were able to complete the given task(s). ALZ's Quicktour scored a feature success rate of 82%, well above the average of 64% for the whole study. For the second aspect, which is a stricter measure of usability, the average score of all animations was 45%. While the Quicktour scored lower in this category, some tasks necessarily failed because the required information was present on the Website, but not included in the Quicktour.
