Technology Acceptance Model
Introduction

This paper studies the progress of the ‘Technology Acceptance Model’ and then goes on to evaluate it from a philosophy of science viewpoint. Technology Acceptance Model (TAM) was introduced in 1989 by Fred Davis to explain the user adoption or acceptance of Information Systems (IS). Based on Ajzen and Fishbein’s Theory of Reasoned Action, which is a psychological theory that explains behavior, TAM has its roots in cognitive psychology and assumes that an individual’s information systems acceptance is determined by two major variables: • Perceived Usefulness (PU) and

• Perceived Ease of Use (PEOU)

The Technology Acceptance Model, version 1. (Davis 1989)
The Technology Acceptance Model (TAM) is considered the most influential and commonly employed theory for describing an individual’s acceptance of information systems. During the past 23 years, the information systems community has considered TAM a parsimonious and powerful theory (Venkatesh and Davis, 2000). Further supporting the notion of TAM’s popularity, Venkatesh and Bala [2008] found that the first two TAM articles, by Davis [1989] and Davis et al. [1989] received 424 journal citations in the Social Science Citation Index (SSCI) by the beginning of 2000 and 698 journal citations by 2003. TAM has been applied to different technologies (e.g. word processors, workstations, WWW, telemedicine) under different situations (e.g. time, culture, geographies) and has undergone a series of empirical, statistical and meta-analysis. Currently, researchers in the IS field consider TAM one of the information systems fields’ own theories, and still put much effort into ongoing research using the theory. Evaluation of TAM using Philosophy of Science – Kuhnian View

The Kuhnian view of philosophy of science accounts for scientific progress through the concept of a paradigm: the common terminology and basic theories of a scientific community. According to Kuhn, scientific...
