Understanding the usage, Modifications, Limitations and Criticisms of Technology Acceptance Model (TAM)

Technology Acceptance Model (TAM) is broadly accepted and has proved applicable in identifying consumers' willingness to utilize information and communication technology (ICT). The theory proposes that Perceived Ease of Use (PEOU) and Perceived Usefulness (PU) are actually determining factors of individual attitudes, while attitude is a determining factor of Behavioural Intention (BI) and Behavioural Intention (BI) influences usage. It is necessary to understand the usage and modifications that have been made to Technology Acceptance Model (TAM) since user acceptance and confidence are of great importance for advance improvement and successful implementation of any new technology. Numerous frameworks and models have been designed and created to describe user acceptance of modern innovations. These models introduced factors that contribute towards user acceptance. This is a review paper on understanding the usage, modifications, limitations, and criticisms of Technology Acceptance Model (TAM). The model has been utilized to measure new different technologies for usage as well as adoption. The literature indicates that the modification of the model was mostly the addition or removal of variables and in some cases the addition of moderators or mediators. The model has limitations identified in literature such as the problem of reliably quantifying behaviour in an observed investigation. Moreover, there are notable criticisms identified in literature such as TAM's incapability of noticing other issues, for example, cost and structural imperatives that pushes users to adopt an innovation. TAM will continue to be accepted and modified according to the successful application of any new technology. This study can be used to enhance users' knowledge of usage, modifications, limitations, and criticisms of Technology Acceptance Model (TAM).
