The usefulness of new technology can be compared to the old technology by scaling. The measurement may be use survey research to outcome of each technology. The measurement tools must test the reliability. In the obvious different of new and old technology may be compared only parameter in each technology.

I think a newer technology should have more benefits and usefulness compare to existing technology thus the term relatively. If we would like to survey the users, we needed the measurement tools comparing between newer and existing technology.

I think that if we want to replacing the old technology by new technology, the new technology should have more benefits than the old technology and can reduce important things like cost and time but still maintain efficiency output or better.
Make sure that useful and make sure that easy to use.
Its can be checked by experts in that field of new technology and survey results with users or people involved in whether that technology is useful or not.

According to the scale items for perceived of usefulness, the new technology should be at least as useful as the old technology with some improvements that can help them in doing their work.

The new technology superseding the old one should have improvements (in short, better) such that its adoption would more perceived to be acceptable by the intended users

– The newer technology should perform better (or at least as good as) than the old one.
– New features or better performance added should be worth an effort to adapt to the newer technology (for instance, if the users have to adapt to the newer system or even change the workflow for the new applications, the newer version of an application must add enough new features or better performance to persuade the users to change)

When replaced an old technology with a new technology, they should better performance than old technology. We should survey outcomes and assess reliability compare with old technology for indicate advantages of new technology.

I think new technology should be more useful, easier to use, and have advantages over the old technology in some ways such as affordable, practical to the actual practice, higher precision, better capacity to detect small specimens, or personalized treatment – highly effective with low adverse event occurrence.

the new technology must be better than the old technology, before creating a new technology an evaluation of the old technology must be carried out to increase user acceptance. new technology should be easier and more useful

When replacing an old technology with a new one, a new technology needs to be expected to provide more benefits, including usable, useful, desirable, and credible than the conventional ones.

New technology should better than the old one in the aspect of usefulness, user friendly, serve the user needs, accuracy and reliability of that particular technology.

While replacing old technology with a new one that is easier to use, it shouldn’t compromise in regards to performance and should give a better outcome.

For this scenario, TAM would suggest that mandatory and compliance-based approaches are not as applicable as the use of social influence. And it would also suggest that practical demonstration of comparing a new technology to an old one showing the effectives and usefulness of the new one are higher than those of the old one would encourage users to increase their intention to use the new system.

Without a doubt, the new technology must be better than the old technology in at least one dimension (e.g., usefulness). However, it is the users who actually use the technology and their attitudes are the most important in the TAM. So, proper change management is necessary in this kind of situation.

The result from TAM could represent the relative usefulness of the new technology such as the new technology could reduce the working time, increase productivity rate, provide more information etc. which reflex the perceive usefulness.

The new tech should doing the same work but faster, cheaper or doing it automatically. That could lead to tech acceptance and changing them into leader of change management to the next wave of change.

Replacing an old technology with a new technology, regarding the TAM suggestion I think that risks and benefits would be considered.
– benefits: cost, time, performance
– risks: security of system or technology, confidentially

New technologies might have more benefits and usefulness compare to existing technologies. However, the change can be step-by-step, start with small pilot setting and then scale up to the whole organization when we see the good results and good practices in real life. This method can allow us to compare results and performance both new and old technologies as the same time and can gain more acceptance when people see the obvious difference.

The perceived usefulness acts as an important role to determine the attitudes of the user. So the new technology should at least show the usefulness or the advantage over the old one such as the new interface, function, operating system, and less complexity that suits to the user.

I think we can change to use the new technology for easier use of the old technology. The TAM uses two factors to determine whether a technology will be accepted by its potential users: perceived usefulness and perceived ease of use. This model emphasizes the perceptions of the potential user. So, if the users realize that using the new technology would be a more accessible effort, they may believe that it would enhance their performance.
