The Technology Acceptance Model (Davis, 1989)

# data[].attributes.body
TAM is the idea that technology adoption is based on a user's perception of a technology's usefulness and ease of use (Hochschule für Technik Stuttgart, n.d.).

It covers

Perceived Usefulness (PU),

Perceived Ease of Use (PEU),

Attitudes toward Using (ATU),

Behavioral Intention to Use (BI) and

Actual System Use (Davis, 1989; Kowalska-Pyzalska, 2024).

# data[].attributes.body
Perceived usefulness means the extent to which a user believes using a technology would improve performance or achieve goals (Dube et al., 2020; Enablers of Change, 2023).

# data[].attributes.body
Users' attitudes toward technology can indicate their intentions to use it (Enablers of Change, 2023).

The more positively someone feels about a technology, the more likely they are to use it; the more negatively, the less likely (Kowalska-Pyzalska, 2024).

Perceived ease of use means the extent to which a user believes using a technology will be "effortless" (Dube et al., 2020; Enablers of Change, 2023).

# data[].attributes.body
Behavioral intention to use proceeds actual use and is someone's intention to or willingness to use a technology (Kowalska-Pyzalska, 2024).

If someone has a strong intention or willingness to use a technology, they are more likely to use it (Kowalska-Pyzalska, 2024).

# data[].attributes.body
Actual system use is the final part of TAM, where users finally use a technology.

It is the real-life, observable, and measurable adoption and use of a technology by a user (Amoroso & Hunsinger, 2009; Kowalska-Pyzalska, 2024).

It seems a lot of literature does not discuss this stage heavily.
