The Technology Acceptance Model (TAM) suggests that the relative usefulness of a new technology is closely related to the perceived usefulness, which is defined as the degree to which an individual believes that using a particular technology would enhance their job performance or make a task easier.
Therefore, if a new technology is easier to use than an old one, the TAM would predict that users would perceive it as more useful and be more likely to adopt and use it. This is because the ease of use of a technology is directly related to the perceived usefulness, as a technology that is easy to use is more likely to be perceived as enhancing job performance or making a task easier.
Moreover, the TAM also takes into account the perceived ease of use, which is defined as the degree to which an individual believes that using a particular technology would be free of effort. If a new technology is easier to use than an old one, it is likely that users would perceive it as having a higher degree of perceived ease of use. This, in turn, would lead to an increase in the perceived usefulness, as a technology that is easy to use is more likely to be perceived as enhancing job performance or making a task easier.
