The document discusses how global companies can convert their global presence into a competitive advantage. It outlines five opportunities for value creation: adapting to local markets, exploiting economies of scale, exploiting economies of scope, tapping optimal locations, and maximizing knowledge transfer. However, pursuing each opportunity also presents challenges that must be addressed, such as increasing costs, isolation from markets, and overdependence on single locations. The document advocates for systematic analysis and continuous adaptation to local needs in order to successfully leverage a global presence.
