Sistema ERP: um estudo de caso sobre o nível de utilização e seu impacto no retorno sobre investimento

Abstract

This dissertation discusses the use and difficulties of obtaining benefits when adopting ERP systems. Although this topic is widely discussed in the literature, there is still a perceived lack of qualitative studies that deepen the understanding. The theoretical framework Acceptance Model Technology (TAM) is perhaps the one that best fits the discussions about the reasons why a new technology is not fully utilized by organizations. In this sense, the main purpose of this study was to evaluate the TAM model and present the main variables that impact on the level of usage of ERP and in addition, empirical data demonstrating the low ROI when using the ERP system is low. The research in this study, therefore examines - in a given organizational context - how to reduce the perception of ease of use and usefulness of ERP through two propositions drawn from qualitative literature: characteristics of initial design and changes in the external environment (business and law). The results of the dissertation show that the company does not use the whole system. Around 30% of the initial, defined design features were no longer used after a certain time. The conclusions suggested from the analysis, found that the design characteristics and changes in the external environment (business and law) influence the low utilization of the system and directly affect the level of use of the ERP system. The appreciated value of the effort expended in these activities and identified cost saving opportunity is $25 million a year, if these activities are executed in the ERP.
