Blockchain technology offers immense potential for increasing efficiency by streamlining business operations. However, blockchain implementation is disruptive and requires high capital organizational processes as it fundamentally re-engineers and automates business processes. By integrating blockchain with Enterprise Resource Planning systems (ERPs), organizations can enjoy the benefits of blockchain adoption with minimal disruption to their business model. The resources regarding integration of blockchain systems and ERP are scarce and dispersed as their applications are in different niches. Thus, there is a need for a study of literature that investigates blockchain and ERP integration and find its key success factors. This systematic literature review (SLR) investigates the key success factors of blockchain and ERP integration and finds the context of integration to derive meaningful insights regarding its application in different functional areas. A list of key success factors is identified. They could be broadly classified into three contexts – technological, organizational, and regulatory. Also important is the environment and sustainability of the integration. This study was able to conclude that the integration of ERP systems with blockchain will enhance the capabilities of current ERP systems by providing value propositions of the decentralized ledgers such as increased transparency, trust, and process automation.
