SUS (System Usability Scale)

The System Usability Scale (SUS) is a simple questionnaire used to evaluate how easy and user-friendly a system, product, or service is. It consists of ten statements about the user’s experience, which respondents rate from "strongly agree" to "strongly disagree." The scores provide insights into the usability of the system, helping designers and developers understand areas for improvement. SUS is widely used in various fields because it offers a quick and effective way to capture user feedback and compare different systems' usability.
