Individual Adoption of IS in Organisations: A Literature Review of the Intention-Based Theories

Abstract:

Users’ perceptions of and intentions to adopt ISs within organisations is an important focus in IS research. In the past several decades, many studies based on different theoretical approaches have been made for predicting, explaining and increasing user acceptance of information systems in the work places. This paper mainly gives a comprehensive review of the intention-based theories of IT adoption, i.e., TRA, TPB TAM, and Triandis’ model. These models have dominated the research on individual adoption of IS in organisations and contribute great knowledge to this research issue. It covers the period from 1989 till the end of 2002 and reviews all articles that have studied some aspects of IS adoption and which have appeared in leading journals in the IS fields. These theories state user adoption and usage behaviours are determined by the intention to use IT, which in turn is influenced by beliefs and attitudes about IT. Since attitudes and beliefs about IT innovations are antecedents of user intention and usage, it is critical to understand the external variables that influence the formation and change of attitudes and beliefs. We describe these theories briefly and summarise review findings according to the component constructs of the theories, i.e., behaviour, behaviour intention, attitudes, beliefs and external variables. We find that the intention-based theories seem to be a very powerful theoretical tool to predict and explain user’s behaviour with regard to technologies within organisation contexts. We still find that behaviour has different dimensions; beliefs are determinants of behaviour and their relationships are complicated. It is crucial to examine the external variables or stimuli effects on other constructs because of their practical implications for management, system design and implementation. This review helps us build a strong knowledge base of users’ behaviour in IS research and could guide our future research in the coming mobile world.
