Enterprise Resource Planning Acceptance Model (ERPAM)

Abstract

Enterprise resource planning (ERP) systems have been implemented in most organizations for few years. But most of the organizations cannot really expose promised benefits of ERP systems. One of the reasons might be ERP users who do not accepted and use ERP system properly. In IT/IS literature organizational users have been exposed as important factor, which has influence on IT/IS acceptance and usage. Technology acceptance model (TAM) proposed by Davis (1989) has been most widely used model for researching user acceptance and usage of IT/IS. While this research is not the first attempt to apply TAM to ERP context, the authors of this chapter aim to make more contributions to the topic. First, they focus on the ERP system use in routine (mature) stage, and because of that, they use construct extended use instead of actual use. In the latest research of ERP system usage, the relationship between work compatibility and usefulness has been examined. New relationships between work compatibility and attitude toward using ERP system have been added. In all TAM studies regarding ERP context, a small number of external factors have been researched. The groups of external factors that have influence on ERP extended usage have been researched. The proposed model has been empirically tested using data collected from a survey of 293 ERP users in 44 organizations across country.
