Which of the following factors influences technology adoption as per the TAM?

The Technology Acceptance Model (TAM) primarily focuses on how perceived usefulness and perceived ease of use influence users' decisions to accept and use technology. Among the options presented, perceived usefulness is a key determinant in the model. It refers to the degree to which a person believes that using a particular technology would enhance their job performance. If users believe that a technology can improve their efficiency or productivity, they are more likely to adopt it.

This intrinsic motivation significantly drives technology acceptance and further usage. Therefore, perceived usefulness is a central concept in TAM, as it addresses the value that the technology brings to its users, directly impacting their willingness to embrace it.

In contrast, while cost of implementation, market trends, and company size may play roles in technology adoption scenarios, they are not central to the TAM framework. These factors can influence wider organizational decisions and strategic considerations, but they do not inherently address user perceptions and attitudes toward the technology itself as effectively as perceived usefulness does. This distinction is crucial in understanding the model and its applications in predicting technology acceptance.
