The TAM explains why people use new technology. TAM says the usefulness of new technology compared to old technology matters a lot. People are more likely to use new things they find helpful and better than the old ones. Perceived usefulness is key to adoption.
When replacing old technology with something easier to use, we need to consider its benefits. If the new technology can provide extra features and improved function, it’s likely to be seen as more useful. If it lacks key features or offers no clear advantage, people might not adopt it.
Usefulness is subjective and varies among different user groups. Considering the user’s needs, preferences, and expectations is required in assessing the usefulness of new technology. User research, feedback, and involving them in development can help ensure the new technology meets their needs and is perceived as valuable.
According to TAM, new, easier-to-use technology should be at least as useful as the old it replaces to get people to use it. Thus, perceived usefulness is important for adopting the new technology.
