This report provides a comprehensive analysis of Tesco's global business environment. It begins with an executive summary outlining the paper's focus on determining Tesco's internal and external environment, followed by an introduction that defines the global business environment and states the report's objective: to determine the strengths, weaknesses, opportunities, and threats (SWOT) of Tesco. The report then delves into a detailed SWOT analysis, examining Tesco's strengths (financial position, brand equity, market share, technological development, and efficient supply chain), weaknesses (failed operations, reduction in operating profit, low-cost strategy, and accounting scandals), opportunities (expansion of Jack's, strategic alliances, online shopping, supplier relationships, and emerging markets), and threats (Brexit, increasing competition, economic crises). The report further explores the impact of political, economic, social, technological, environmental, and legal factors on Tesco's marketing and operations departments. The report concludes that Tesco, a well-established global brand, needs to leverage its strengths and address weaknesses while capitalizing on emerging opportunities and mitigating threats to maintain its market position.
