This report provides a detailed analysis of the business environment, focusing on Marks and Spencer (M&S). It begins by exploring different types of organizations, their purposes, and legal structures, including public, private, and voluntary sectors, and relevant legislation such as the Partnership Act 1890 and Companies Act 2006. The report then examines the size and scope of various organizations (micro, small, medium, and large), relating them to M&S's PLC status. It proceeds to analyze the interrelationship between organizational functions like HRM, marketing, IT, production, finance, and R&D, highlighting their importance for achieving business objectives. The report further investigates the macro environment's impact on M&S using PESTEL analysis, covering political, economic, social, technological, environmental, and legal factors. Finally, it conducts an internal analysis of M&S, assessing its strengths, weaknesses, and how they relate to the external macro environment. The report concludes with an evaluation of M&S's overall business strategy and performance.
