The success of any technology innovations lead by the acceptance of end user, many IT implementations failed as it’s not accepted by the user group. ERP being the strategic application require more insights in this regard as failure rate of ERP application are very high i.e. 7 out of 10 due to lack of consideration of CSFs in ERP implementation process. Said study aims at providing an alternative view of users' enterprise resource planning (ERP) acceptance. Despite the large body of literature, there are still empirical inquiries to investigate the ERP system implementation from end-users' perspectives as well as from different organizational contexts, for the said research researcher consider the Higher educational institute. Survey based method is imposed to gather end-users' perception, and in the end, with their behavioral intention of using the ERP system. In doing so, this study incorporates the best practices of ERP system implementation projects Users participation and adoption into the extended technology acceptance model (TAM) that includes belief constructs and socio environmental construct (subjective norm). The empirical analyses show that managerial practices and socio environmental factor are significantly related to the original TAM variables in the context of ERP system. Positive effect on the perceived ease of use, suggesting a useful reference for future research.. This study would also benefit other sectors by offering valuable end users insights that enable them to appreciate and improve end-users' ERP system acceptance and Adoption.
