Acceptance and usage of ERP systems: The role of institutional factors in ERP post-implementation

One important challenge in ERP implementation is the acceptance and usage of ERP systems by their users. This study aims to identify important antecendents of ERP acceptance and usage among individual users, considering specifically the complex nature of ERP systems. A research model was developed, incorporating two antecedents from DeLone and McLean IS success model, two technological related antecedents and three antecedents related to institutional support in the post-implementation stage. A total of 173 sample was collected through a survey among ERP users working in three large firms in Indonesia. The model was validated and 14 hyphoteses were empirically tested using structural equation modeling (SEM) technique. The results support the proposed model to a large extent, highlighing the importance ERP symbolic adoption for ERP use, managerial commitment and technical support as the antecedents related to institutional support, and perceived fit and perceived dependability as the antecedents related to technology characteristics.
