The Technology Acceptance Model (TAM) is a well-known theory for understanding user acceptance of technology, while the System Usability Scale (SUS) is a tool for measuring perceived usability.  Elaboration: Technology Acceptance Model (TAM): TAM is a model that helps explain why people are more or less likely to use a new technology. It focuses on two key factors:  Perceived Usefulness: The degree to which a user believes using a system will help them perform their work better.  Perceived Ease of Use: The degree to which a user believes using a system will be effortless.  System Usability Scale (SUS): SUS is a questionnaire designed to assess the overall usability of a system. It consists of 10 questions that users respond to, with scores ranging from 0 to 100. Higher scores indicate better perceived usability.  Relationship between TAM and SUS: SUS can be used as a measure of perceived ease of use within the TAM framework. Studies have shown that integrating TAM and SUS can provide a more comprehensive understanding of user acceptance and usability.  Example: Researchers may use SUS to assess the ease of use of an e-learning platform, while also using TAM to understand the factors influencing students’ overall acceptance of the platform.
