An Investigation of End-Users Acceptance Of Enterprise Resource Planning Systems at the Post-Implementation Phase in Mid-Sized Public Organisations In Tanzania

The Enterprise resource planning (ERP) systems is, described as a package business software system with a database that allows an organisation to automate and integrate its business processes, share common data and practices across its units, in a real-time environment. This study aimed at investigating factors that affect the end-users acceptance of the ERP system during post-implementation phase in Tanzania. The quantitative approach was used. Three mid-sized public organisations in Tanzania who are at the post-implementation phase of ERP systems implementation were randomly selected and the 70 end-users in these organisations were administered with a questionnaire based on the UTAUT model. The model also assisted in generating the study hypothesis from its main dimensions. The hypotheses were then tested by regression analysis of the data generated by the questionnaire and the relationships among the study variables were established. The unit of analysis was individual respondents. The results show that performance expectancy, effort expectancy, social issues and facilitating condition affect end-user acceptance of ERP systems; all had a significance of below 0.05. The major conclusion of the study is that all the four dimensions (Performance expectation, Effort expectation, Social influence and Facilitating conditions) of the UTAUT model are indeed factors that influenced in varied magnitude the end-user acceptance of ERP systems in mid-size public organisations in Tanzania, Thus it is recommended that organisations need to pay close attention to these dimensions in order to improve end-user ERP acceptance
