This presentation provides an analysis of Tesco's business environment using the PEST (Political, Economic, Social, Technological) analysis and Porter's Five Forces model. The PEST analysis examines external factors such as tariff policies, inflation rates, changing social attitudes towards health, and technological advancements that impact Tesco's operations. Porter's Five Forces model assesses the threat of new entrants, competitive rivalry, the threat of substitutes, and the bargaining power of both suppliers and buyers. The presentation concludes that PEST analysis is crucial for understanding changing trends and enabling timely corrective actions within the business environment. The analysis references academic sources to support its findings.
