Further, Porter cites "linkages" as a driver to sustainability. Linkages
are ties "which require coordination across organizational lines
or with independent suppliers or channels" (p. 112). The Council of
Logistics Management (1998) defines logistics as, "that part of the
supply chain process that plans, implements, and controls the efficient
flow and storage of goods, services, and related information from the
point of origin to the point of consumption in order to meet customers'
requirements." In essence, the flow and storage aspects of Porter's
definition of "linkages" is logistics.
