The Technology Acceptance Model (TAM) is an information-systems theory, introduced by Fred Davis, that predicts user adoption of a technology from two key beliefs: perceived usefulness and perceived ease of use. These beliefs shape attitudes and behavioural intention, which in turn drive actual usage. TAM is one of the most widely applied frameworks for explaining and forecasting the uptake of new technologies.

- TAM posits a causal chain in which external factors influence two core beliefs, perceived usefulness and perceived ease of use, which jointly determine attitude, behavioural intention, and ultimately use. Successors such as TAM2 and UTAUT extend the base model with social, facilitating, and experiential variables. Researchers apply it to forecast adoption of products from enterprise software to AI assistants, using survey instruments to estimate the strength of each pathway.
