A Review of Customer Relationship Management Systems

Abstract

Customer Relationship Management (CRM) systems are central to modern organizational strategies aimed at acquiring, retaining, and developing profitable customer relationships. Advances in information technology, data analytics, artificial intelligence, and cloud computing have transformed CRM from a transactional database tool into a strategic, enterprise-wide system supporting customer-centric decision-making. This review synthesizes foundational theories, technological architectures, and contemporary CRM practices, including operational, analytical, collaborative, social, and AI-enabled CRM systems. Through a comparative analysis, the paper evaluates strengths, limitations, and application contexts of CRM system types. The discussion highlights strategic alignment, data governance, and organizational integration as critical success factors, while the conclusion outlines managerial implications and future research directions in intelligent and ethical CRM systems.
