In other words, supply chains make up a network of different companies that closely cooperate to deliver goods.2.1.2 The definition of Supply Chain ManagementThe Council of Supply Chain Management Professionals defines SCM this way: “The Supply Chain Management encompasses planning and management. of all activities involved in sourcing and supply, conversion and all logistics activities. Importantly, this also includes coordination and collaboration with channel partners, who may be suppliers, intermediaries, third-party service providers and customers. Essentially, supply chain management integrates the management of supply and demand within and across businesses. “Based on the definitions given by APICS and CSCMP, we believe that SCM is much broader than core functions such as manufacturing, distribution and logistics. It can contribute to information flows between organizations and their suppliers to eliminate the bullwhip effect and also increase productivity and capabilities within the enterprise..
