Evolution Of Supply Chain Management
Supply chain network Management Strategy and Capabilities evolved from primitive to esoteric in the four decades since the mid-1970.
In the initial phase (pre-1950), there was no need of any strategy for supply chains. In the decade that followed, supply chain strategy focused only on the overall profitability of the business.
Supply Chain strategy came into real existence only after the Materials requirements Planning revolution of the 1980s.
Five Things To Avoid In Supply Chain Management.
Companies became aware of the growing material scarcity and started optimizing resources. Strategic activities were in the hands of a few key people in the organization.
Strategic planning was highly inefficient due to a lack of data in a standard format. Planning was done without addressing ground-level problems.
The MRP revolution evolved into Enterprise Resource Planning (ERP) during the 1980s and the 1990s.
The strategy was based on the “PUSH” model. Enterprise-wide supply chains were capable of collectively forecasting the supply and demand levels.
The 1990s and early 2000s’ ERP revolution led to a migration from a PUSH model to a PULL methodology (build-to demand).
