9. THE TAM The Technology Acceptance Model (TAM) is an information systems theory that models how users come to accept and use a technology. The model suggests that when users are presented with a new technology, a number of factors influence their decision about how and when they will use it, notably:information systems Perceived usefulness (PU) - This was defined by Fred Davis as "the degree to which a person believes that using a particular system would enhance his or her job performance". Perceived ease-of-use (PEOU) - Davis defined this as "the degree to which a person believes that using a particular system would be free from effort" (Davis 1989).Davis 1989 Source: Dennis Galletta - Applying TAM across cultures: the need for caution

11. TAM IN APPLICATION “We interpret this to mean that low UA individuals do not appear to need the added assurance of usefulness and ease of use exhibited by high UA individuals. Usefulness therefore seems to be unaffected by ease of use when people are not strongly seeking to avoid uncertainty.” “Our interpretation is that when an authority figure recommends or requests the use of a system in a high PD culture, users will not need the added attraction of usefulness and ease of use to make use of the system. The recommendation is enough for those with high PD, those individuals who exhibit the cultural characteristic of respecting those of higher authority.”

12. TAM IN APPLICATION CONT’D “High Masculinity individuals are likely to be more concerned with accomplishing their goals, and less concerned with usability of technology. Their higher self-confidence brings a powerful assumption that they will be able to use the technology to their advantage.” “We believe that people who focus on Collectivism are more willing to suffer with lower usability to accomplish the goals valued by others. They would focus less on their own effort and more on what seems to be valued or needed by others (including not only colleagues, but superiors as well).”

13. IN LESS WORDS Low Uncertainty Avoidance, high Masculinity, high-Power Distance, and high Collectivism strongly impact the effects of Perceived Ease of Use and/or Perceived Usefulness.
