This report provides a comprehensive analysis of TESCO's business environment. It begins by defining the business environment and introduces the structure of the report. The report explores different types of organizations (public, private, and voluntary sectors), their purposes, and legal structures, using NHS and Oxfam as examples alongside TESCO. It then examines the size and scope of these organizations. The core of the report focuses on the relationship between organizational functions (marketing, finance, and HRM) and how they link to organizational objectives and structure, specifically within TESCO's hierarchical structure. The report further identifies the positive and negative impacts of the macro environment, using PESTEL analysis to assess political, economic, social, technological, environmental, and legal factors affecting TESCO, with Brexit as a key example. Finally, the report conducts internal and external analyses to identify TESCO's strengths and weaknesses and explains how these interrelate with external macro factors, concluding with an overview of the key findings.
