Book excerpt: Global Business Strategy looks at the opportunities and risks associated with staking out a global competitive presence and introduces the fundamentals of global strategic thinking. The authors demonstrate how a company should change and adapt its domestic business model to achieve a competitive advantage as it expands globally. Our framework includes a company’s business model, the strategic decisions a company needs to make as it globalizes its operations, and globalization strategies for creating a competitive advantage. A business model has four principal dimensions: market participation, the value proposition, the supply chain infrastructure, and its management model.
