  • The System Usability Scale (SUS) is a widely used tool for evaluating the usability of software, websites, and other interactive systems.
  • The SUS consists of ten statements related to a user's experience, along with a five-point Likert scale.
  • The goal of the SUS is to gather quantitative data that can help gauge how user-friendly a system is.
  • The SUS is used in various industries, including technology, healthcare, e-commerce, finance, education, and automotive.
  • The SUS promotes consistency in usability evaluations and provides a standardized questionnaire for measuring user experience.
