The effect of computer self-efficacy on enterprise resource planning usage

Global competition has impelled numerous organisations to employ enterprise resource planning (ERP) systems, although quite frequently without success. Studies have demonstrated that a major factor for failure is employee resistance in organisations using these systems. Exactly the factors that facilitate ERP adoption among users have seldom been identified. This study examines the usage behaviour of a sample of users of the new technology of ERP system using a technology acceptance model (TAM). Furthermore, this paper incorporates an additional behavioural construct, computer self-efficacy (CSE), to improve the predictive value of the original TAM model, named revised TAM. Additionally, the structural equation model (SEM) is used to verify the causal relationships between variables. Analytical results confirm that not only is the TAM appropriate for explaining the use of ERP, but that incorporating CSE enhances the power of the model.
