The History of the SUS

Developed by John Brooke at Digital Equipment Corporation in 1986, the System Usability Scale has been widely used in the evaluation of various systems. Bangor, Kortum, and Miller have extensively used the scale over a ten-year period, producing normative data that allow SUS ratings to be positioned relative to other systems.
