This report provides a comprehensive environmental analysis of Marks and Spencer (M&S), a British multinational retail company. The analysis begins with an introduction to the company, its history, and its competitors, including ASDA, ALDI, and Tesco. The core of the report focuses on an external environment analysis using the PESTLE model, examining political, economic, social, technological, legal, and environmental factors impacting M&S. Political factors include free trade policies and Brexit; economic factors cover economic recession and its impact on consumer behavior; social factors consider online shopping and the demand for organic products; technological factors highlight digital marketing and self-checkout systems; environmental factors address sustainable practices; and legal factors involve trade regulations. A SWOT analysis is also conducted, evaluating M&S's strengths (brand recognition, wide product variety), weaknesses (decreasing sales, manual processes), opportunities (global expansion, online stores), and threats (competition). The report concludes with recommendations based on the findings.
