In systems engineering, the system usability scale (SUS) is a simple, ten-item attitude Likert scale giving a global view of subjective assessments of usability.It was developed by John Brooke [1] at Digital Equipment Corporation in the UK in 1986 as a tool to be used in usability engineering of electronic office systems.
The QUIS is currently at Version 7.0 with demographic questionnaire, a measure of overall system satisfaction along 6 scales, and measures of 9 specific interface factors. These 9 factors are: screen factors, terminology and system feedback, learning factors, system capabilities, technical manuals, on-line tutorials, multimedia ...
The questionnaire is a seven-point Likert scale in which scale 1 indicates the task as ‘very difficult’, and scale 7 indicates the task as ‘very easy’. [ 12 ] System Satisfaction is used to evaluate the overall usability of the apps through System Usability Scale (SUS), which is a usability assessment questionnaire with reliable and ...

A feature found in the Official NASA TLX App is a new computer interface response rating scale, termed a Subjective Analogue Equivalent Rating (SAER) scale, that provides the closest possible user experience to that found in the paper and pencil version of NASA TLX.
Usability goals must be included in every product design process that intends to follow a Human Factors approach (for instance, User-centered design [1] process or Usability Engineering Lifecycle [5] [full citation needed]). They have to be clearly stated from the onset of the process, as soon as the end-users needs, risk of use, contexts and ...
The average rating on these six statements is regarded as the user's usability rating of the interaction component. Based on lab studies with difficult to use interaction components and easy to use interaction components, a break-even point of 5.29 on seven-point Likert scale has been determined. [4]
Paper prototyping of a website interface. In human–computer interaction, paper prototyping is a widely used method in the user-centered design process, a process that helps developers to create software that meets the user's expectations and needs – in this case, especially for designing and testing user interfaces.
