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 ...
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’.
The success of an IR system may be judged by a range of criteria including relevance, speed, user satisfaction, usability, efficiency and reliability. [2] Evaluation measures may be categorised in various ways including offline or online, user-based or system-based and include methods such as observed user behaviour, test collections, precision ...
Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability.
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.
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 ...
[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 ...
