| Summary≠ | The Technology Acceptance Model (TAM) is a theoretical model of why people accept or reject information technology, introduced by Fred Davis in 1989. Adapting the Theory of Reasoned Action, it posits that two beliefs—perceived usefulness and perceived ease of use—shape attitudes and behavioural intention toward a system, which in turn drives actual use. The constructs are measured with validated survey scales and the relations are typically estimated as a structural equation model. | The Bass diffusion model is a parsimonious mathematical model of how a new product or technology spreads through a market over time, introduced by Frank Bass in 1969. It represents adoption as the combined effect of two forces—external influence (mass media, advertising) acting on innovators and internal influence (word of mouth, imitation) acting on imitators—producing the characteristic S-shaped cumulative adoption curve from a fixed pool of eventual adopters. |
