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.
It is arranged in a hierarchical format and contains: (1) a demographic questionnaire, (2) six scales that measure overall reaction ratings of the system, (3) four measures of specific interface factors: screen factors, terminology and system feedback, learning factors, system capabilities, and (4) optional sections to evaluate specific ...
Hallway testing, also known as guerrilla usability, is a quick and cheap method of usability testing in which people — such as those passing by in the hallway—are asked to try using the product or service. This can help designers identify "brick walls", problems so serious that users simply cannot advance, in the early stages of a new design.
Usability engineering is a professional discipline that focuses on improving the usability of interactive systems. It draws on theories from computer science and psychology to define problems that occur during the use of such a system. Usability Engineering involves the testing of designs at various stages of the development process, with users ...
While holistic oriented usability questionnaires such as the system usability scale (SUS) examine the usability of a system on several dimensions such as defined in ISO 9241 Part 11 standard effectiveness, efficiency and satisfaction, a component-based usability questionnaire (CBUQ) [4] is a questionnaire which can be used to evaluate the ...
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 valid results. It includes ten questions, each with five items ranging from ‘strongly agree’ to ‘strongly disagree’.
Usability testing methods aim to evaluate the ease of use of a software product by its users. As existing methods are subjective and open to interpretation, scholars have been studying the efficacy of each method [1] [2] [3] and their adequacy to different subjects, comparing which one may be the most appropriate in fields like e-learning, [4] e-commerce, [5] or mobile applications.
[1] [2] [full citation needed] For this assessment to be objective, there is a need for measurable goals [3] (for instance in terms of easiness of use or of learning) that the system must achieve. That kind of goal is called a usability goal (or also usability requirement [1] [4]). They are objective criteria against which the results of the ...
