Most organizations are simultaneously members of a number of supply chains. An organization in a chain purchases materials and services from anumber of suppliers, and convertsthem into a range of products that they sell to other organizations. Successful companies use their logistics competence to optimize their operations in managing the materials flow through their companies. But it will no longer be necessary or desirable for each supply chain member organization to only manage its logistics activities on an independent basis. However it is most unlikely for any one company that all the supply chains in the diagram will require formalized supply chain management processes. It is a requirement for thatorganization to focus its supply chain efforts on those networks that are critical to the success of the company. Questions: 1.Most organizations are members of a number of supply chains.
