The document outlines 5 stages of internationalization: 1. Domestic operations where a firm only operates within its home country. 2. Export operations where a firm expands by exporting products internationally while keeping production domestic. 3. Subsidiaries or joint ventures where a firm physically moves some operations abroad through partnerships. 4. Multinational operations where a firm establishes assembly facilities across several countries and regions globally. 5. Transnational operations where firms function as truly global companies achieving both global efficiency and local responsiveness.
