Organisations have made significant investments in enterprise resource planning (ERP) systems with the strategic expectation that employees will utilise this technology to enhance organisational performance. However, research indicates that ERP systems are underutilised. In order to disentangle the challenge of underutilisation, this paper addresses the impact of organisational control and empowerment on infusion—the deep and comprehensive usage of an information system. Moreover, it also tests whether infusion will lead to higher levels of ERP system success. Data from a sample of 260 matched pairs of ERP system users and their supervisors were collected and analysed. Results indicate that empowerment is positively related with infusion, whereas an inverted u-relationship has been found for organisational control. The critical link between infusion and ERP system success was found as well, meaning that the more users utilise the system to its fullest extent, the more likely the organisation is to attain ERP systems' promised benefits.
