Impacts of TAM-based External Factors on ERP Acceptance

Enterprise resource planning (ERP) solutions have been implemented in most companies recently, but it seems that the companies who use ERP solutions are unable to point out the most important contributions of their ERP systems. One of the reasons for this might be that users do not accept and use the ERP solution properly. The technological acceptance model (TAM) proposed by Davis (1989) has been the most widely used model for researching user acceptance and usage of IT/IS. Although our research is not the first to apply TAM to an ERP context, we aim to make additional contributions to the existing body of literature. First, we focus on ERP system use in companies’ maturity phase. Second, we expose and examine three groups of external factors which influence ERP usage. The model was empirically tested using data collected from a survey of ERP users in 44 organizations. For analysis PLS was used.
