Supply Chain Management (SCM) covers the planning and control of both the physical movement of materials and the resources used in the supply process from raw materials to consumable products. The SCM process represents a single “value chain” targeted to achieve defined corporate goals by adding value to a product in terms of time and place within the overall corporate offer. The significant elements of the supply chain include: Supplier management (internal or external); Inbound logistics; Process logistics; Outbound logistics to customers (and returns), and Customer management SCM is about identifying the relationships both within each element of the supply chain and between the elements comprising of the supply chain for a product. It is particularly about identifying those uncertainties which affect both performance and behaviour within the supply chain as a whole.
