The model was developed by Fred Davis in 1989 and has since been widely used to understand and predict user behavior towards technology.
The TAM is based on two main constructs: perceived usefulness (PU) and perceived ease of use (PEOU). Perceived usefulness refers to the degree to which a user believes that a technology will enhance their job performance or achieve their goals. Perceived ease of use, on the other hand, refers to the degree to which a user believes that a technology is easy to use.
According to the TAM, these two constructs directly affect a user’s attitude towards using technology, which in turn influences their intention to use the technology. Other factors, such as social influence and system characteristics, can also influence a user’s intention to use technology.
The TAM has been widely applied in various fields, including information systems, e-commerce, and healthcare. It has been used to understand user behavior towards a wide range of technologies, from simple mobile applications to complex enterprise systems.
Overall, the TAM provides a useful framework for understanding and predicting user behavior towards technology, and can help designers and developers create more user-friendly and effective technologies.
