Evolution of the Concept of Supply Chain Management

The transformation of Supply Chain Management over time has been characterized by a progressive fusion of previously disparate tasks. This trend gained significant traction in the 1960s, driven by the recognition of its potential to amplify productivity within a historically fragmented system. While the fundamental principles governing logistics have endured, there was an initial consolidation phase that unfolded during the 1970s and 1980s, delineating two primary spheres: materials management and physical distribution.

The subsequent evolution in the 1990s was propelled by the globalizing forces, compelling the convergence of functional domains and giving birth to a more holistic understanding of logistics. However, it was the advent of information and communication technologies that acted as the catalyst for an even more profound transformation, ushering in the modern concept of supply chain management. This paradigm shift facilitates the harmonized orchestration of information, financial operations, and the intricate movements of goods. As a result, this evolution has opened up novel avenues for production and distribution methodologies that were previously unattainable.
