This report provides a comprehensive analysis of international business strategy, focusing on multinational enterprises and the frameworks used to assess their operations. It begins by outlining the key features of multinational enterprises, including their global reach, high earnings, and strategic investments in marketing and production.

Furthermore, it delves into the internal environment of a corporation through VRIO analysis, assessing value, rarity, imitability, and organization, with Sainsbury's as a case study. Finally, the report uses SWOT analysis to evaluate Sainsbury's strengths, weaknesses, opportunities, and threats, considering factors such as customer relationships, financial performance, market competition, and the impact of events like the Covid-19 pandemic. The analysis highlights the importance of adapting to market developments and leveraging technology to maintain competitiveness.
