A Systematic Review of ERP, CRM, and HRM Systems for SMEs: Managerial and Employee Support

This systematic review examines the role of Enterprise Resource Planning (ERP), Customer Relationship Management (CRM), and Human Resource Management (HRM) systems in enhancing managerial decision-making and employee productivity in small and medium-sized enterprises (SMEs) between 2014 and 2024. It explores how these systems streamline operations, improve workflow automation, and support real-time communication, helping SMEs overcome resource limitations and enhance operational efficiency. Additionally, the review considers how these integrated technologies, particularly when combined with advancements such as artificial intelligence (AI) and machine learning (ML), contribute to better resource allocation, strategic planning, and long-term business performance. In addressing the challenges SMEs face in system adoption—such as costs, training, and implementation—the review offers actionable insights into how ERP, CRM, and HRM systems can be strategically employed for sustainable growth and competitive advantage.
