Abstract

The System Usability Scale (SUS) was administered verbally to native English and non-native English speakers for several internally deployed applications. It was found that a significant proportion of non-native English speakers failed to understand the word “cumbersome” in Item 8 of the SUS (that is, “I found the system to be very cumbersome to use.”) This finding has implications for reliability and validity when the questionnaire is distributed electronically in multinational usability efforts.
