In the context of the TAM, the model suggests that perceived usefulness is a crucial factor influencing users’ acceptance and adoption of technology. If you are replacing an old technology with a new one that is more useful and facilitates easier completion of tasks, the TAM would generally suggest that the new technology should be perceived as at least as useful as the old technology, if not more useful.
The TAM posits that users are more likely to accept and adopt a new technology if they perceive it as providing value, benefits, and usefulness in their tasks or activities. Therefore, when introducing a new technology, it’s essential to ensure that users perceive it as delivering at least the same level of usefulness, if not greater, compared to the old technology.
In summary, the TAM implies that the relative usefulness of the new technology, in comparison to the old one, is critical for successful adoption. Therefore, efforts should be made to communicate and demonstrate the enhanced or at least equivalent value that the new technology brings, using persuasive messages that highlight its user-friendly and efficient features.
