Technology Acceptance Model Template – Products, software, websites and applications should also be used and useful for everyone “to get” them, both in their personal and professional lives.
This is the idea behind the influential technology model (Tam). Here are 10 things to know about Tam.
Technology Acceptance Model Template
1. If you build it, will they come? Fred Davis developed the first incarnation of the technology model more than three decades ago at the time of Su. It was originally part of the mit number in 1985. Companies want to know if all investments in new computer technology will be valid. (This is before the Internet as we know and before Windows 3.1.) The use will be an essential ingredient to evaluate productivity. There is a reliable and valid means that can be explained and predicted to be valid for both software and IT managers.

2. Cognitive benefits and easy to use drive. What are the main causes of application and use? There are many variables but two of the biggest factors appearing from previous studies are aware that technology does something useful (using cognitive; u) and it is easy to use (easy use; e). Davis then started with these two buildings as part of Tam.
3. Psychological verification from two studies. In order to create items for Tam, Davies followed the process of building a classical test theory (CTT) (similar to our SUP-Q). He reviewed the digits about the application of technology (from 37 articles) and created 14 candidates each for the benefit and easy to use. He checked them in two studies. The first study was a survey with 120 people participating in IBM on the use of email programs, which revealed six items for each party and eliminating negative goals that reduce reliability (similar to detection. our). Two graphic programs of IBM.
4. You can change the balance of feedback. The first study described by Davis used a screen/disagreement with 7 points, similar to PSSUQ. In the second study, the ladder is different from the 7 -point reasonable scale (the most unreasonable possibility) with all the points with titles.
Jim Lewis recently tested four -scale variants with 512 comments IBM (yes, Tam and IBM have a long and continuous history!). He changed the three items to measure the real and unexpected experience (see Figure 3 below) and compare different ratio versions. He could not find statistics in four versions and all reasonable can be predicted for the same use. But he found more important feedback when the labels “agreed” and “the most reasonable” were placed on the left. Jim proposed a more familiar agreement (with disagreement on the left and a lot on the right) as shown in Figure 3.

5. This is a developing model and is not a static question. M is designed for the “model” because the idea is that many variables will affect the application of technology and each variable is measured through different questions. Academic favorite models and the reason are very reliable science on models to explain and predict complex results, from the probability of roller position 6, attractive and people. In fact, there are several three: Davies Tam, Tam 2 originally including other buildings presented by Venkatesh (2000) [PDF] and Tam 3 (2008) even many variables (for example: owner Overlooking, subjective standards, relevant to work, the quality of the output and sampling results). These extensions for the original triangle model show the increasing desire to explain the application (or absent) of technology and identify and measure many external variables. It is found that there have been many tam studies that are controlling benefits and easy to use functions through use. Or as Davis said, “Users are often ready to deal with some difficulties in using an important function system seriously.” This can be seen in the original triangle model in Figure 1, easy to use through the ability to use outside the positions.
6. Items and scale have changed. In the development of Tam, Davis defeated items from 14 to 6 for easy and beneficial structures. Tam 2 and Tam 3 only use four items for each building (items with the upper flower mark above and a new “mental effort” item). In fact, another article of Davis et al. (1989) Only use four. Need to reduce the number of items because many variables are added, you need more items to measure these buildings and the questionnaire of 80 items will not be realistic and painful. This once again emphasizes Tam as more models and fewer standard questions.
7. He predicts the use (valid access). The basic newspaper (Davis, 1989) shows the correlation between the current use and the higher reporting (R = 0.56 for benefits and R =. The participants are also required to predict The use of their future and for this front is easily adjusted and benefits in both pilot research (R = 0.85 for benefits and R =. From participants at the same time (not a vertical component) and it has the effect of strengthening the adapter. Another study of Davis et al. (1989) is really a vertical component. ; 14 weeks later, those students answered Tam and used questions themselves. The same converter has been valid by explaining 45% of the intention of behavior, which has established a certain level of visual validity. The later studies of Venkatesh et al. (1999) also found a correlation of R = 0.5 between behavioral intentions and practical use and self -assessment.
8. This expands other behavioral prediction models. Tam is an expansion of the common theory of Ajzen and Fishbein’s reasonable actions but applies to specific computer fields. Trama is a model that suggests that voluntary behavior is a function of what we think (belief), what we feel (attitude), our intentions and subjective standards ( What other people think is common). Tam stated that our beliefs about easy and benefits affecting our use, which affects our intentions and practices. You can see the similarity in the test model in Figure 4 below compared to Figure 1 above.

9. There is no standard. Despite being widely used, there is no data published in the total number of points, not because of its ability to use and easy to use. If there is no measure, it is difficult to know whether a product (or technology) has recorded enough to know if the potential user or currently found it useful or not (and applied it or continued to use) .
10. Umux-lite is a triangle treatment. We talked about Umux-Lite in a previous article. It has only two items that provide a similar formula for the items in the original categories: [This system] meets my requirements (which is the map of the benefit component) and [this system] It is easy to use (that is the map to the light composition). Our previous research shows that even individual items are often enough to measure a structure (as easy to use). We hope Umux-Lite will increase in the UX industry and help create data (which we will also help!).
Thanks to Jim Lewis for providing a manuscript of his article and commented on a manuscript of this article. Technology receipt (Tam) is a theoretical framework developed to explain how to use efforts and technology. This is a model that is widely used in different fields, including information systems, marketing and social sciences. Tam was first provided by Fred Davis in 1986 and has since changed and expanded by some researchers.

Tam is made up of two basic components: feeling (PU) and easy to use (People). PU refers to learning in which users believe that technology will improve their performance or output. Fu refers to learning that users believe that technology is easy to use. According to Tam, these two factors are the main decisions of the reception of users and behaviors.
Although PU and People are the main cause of the Three, external factors can also affect users and use. These factors include social standards, organizational factors and personal differences.
