What Supply chain management is
A subset of value chain management, it is an old system that's been updated with new technology. It specifically refers to the relationship between a supplier and a retailer. For example, a major retailer can monitor surplus on its shelves right down to an individual product, and this enables the retail store to keep its supplier aware of how its product is selling. In return, the retailer may demand favorable promotions from the supplier.
