The term "Enterprise Resource Planning (ERP) System" is commonly used by academics and practitioners in business and information systems. This research reveals two interpretations of the term ERP system, which implies that defining ERP systems comprehensively poses challenges, prompting a focus on their inherent characteristics. Using Design Science Research Methodology, this study aims to provide clarity by introducing a continuum framework that categorizes ERP system implementations based on their software architecture and ERP system characteristics. The framework serves as a guiding tool, enhancing understanding of ERP systems and facilitating ways to increase efficiency and effectiveness. To illustrate its practical utility, the framework is applied in a case study context. The paper concludes by identifying avenues for future research and addressing inherent limitations.
