Quo vadis, TAM?

HEC Montréal henri.barki@hec.ca The Technology Acceptance model (TAM) is one of the most influential theories in Information Systems. However, despite the model 's significant contributions, the intense focus on TAM has diverted researchers’ attention away from other important research issues and has created an illusion of progress in knowledge accumulation. Furthermore, the independent attempts by several researchers to expand TAM in order to adapt it to the constantly changing IT environments has lead to a state of theoretical chaos and confusion in which it is not clear which version of the many iterations of TAM is the commonly accepted one. The present commentary discusses these concerns, speculates on the possible contributions to the current state of affairs, and makes several suggestions to alleviate the problems associated with TAM and to advance IT adoption research to the next stage.

Quo vadis, TAM?

1. Introduction
The Technology Acceptance Model (TAM) is generally referred to as the most influential and commonly employed theory in information systems (Lee et al. 2003). Some also consider it to be the only well-recognized theory in IS (having dethroned
Nolan’s stage model that had this distinction earlier). The objective of the present commentary is to draw researchers’ attention to the necessity of reorienting IT adoption and acceptance research toward potentially more fruitful avenues and away from “TAM++ research” that adds little knowledge to TAM or its many different versions.
The origins of TAM can be traced to the Theory of Reasoned Action (TRA) (Fishbein and Ajzen 1975). TRA requires that salient beliefs about one’s attitude toward a particular behavior (e.g., buying on the web) be elicited in order to be

    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.…
