Keynote:

The System Usability Scale: Past, Present, and Future

Despite being described by its developer as a “quick and dirty” usability scale, the System Usability Scale (SUS), developed in the mid-1980s and first published in the mid-1990s, has become a popular questionnaire for end-of-test subjective assessments of usability. For example, the SUS accounted for 43% of post-test questionnaire usage in a recent study of a collection of unpublished usability studies. Research conducted on the SUS in the past ten years has shown that although it is fairly quick, it does not appear to be dirty. This speech will cover (1) the development and proliferation of the SUS, (2) a summary of key research on the SUS from 2008 through 2016, (3) details about some of the latest (and in several cases not yet published) research on the SUS, and (4) what the future holds for the SUS, which will be 32 years old in 2018.
