Managing the supply chain is a core competence that the organization must possess to deliver profit and return on investment (ROI).

Virtual integration is achieved by firms collaborating in partnership (alliance), which is also referred to in the literature as the extended enterprise, strategic network or virtual corporation. Figure 10.1 illustrates how supply chain strategies can impact upon sales revenues and costs and how total profit is affected as a consequence.
