Perceived usability: Usefulness and measurement of this construct

In addition to efficiency and effectiveness, perceived usability is an important component of the classical conception of usability. However, there have been recent criticisms of the usefulness of perceived usability. This talk will survey this literature.

Over many years, several scales have been developed to measure perceived usability or similar concepts, including SUS, UMUX-LITE, TAM, and NPS. This talk will review leading scales, with an in-depth focus on practical guidance on UMUX-LITE.


PRESENTER: James R. (Jim) Lewis is Distinguished User Experience Researcher at MeasuringU.com. He has published influential papers on the topic of this talk, the assessment of perceived usability, and written books on the the broader topic of quantitative user research, including Quantifying the User Experience (with Jeff Sauro).  As well, Jim has had a long and broad career designing and evaluating user interfaces (graphical, spoken, mobile), including the first smart phone, the Simon. He holds a master's degree in human factors psychology and PhD in psycholinguistics.
