This report provides an analysis of the business environment, focusing on different organisational types, their functions, and structures. It begins by defining organisations and their purpose, differentiating between the private, public, and voluntary sectors. The report then delves into the legal structures within the private sector, such as sole traders, private limited companies (LTD), and public limited companies (PLC). It also outlines the characteristics of the public and voluntary sectors. The core of the report involves case studies of three organisations: Boohoo (a PLC in the private sector), the British Broadcasting Corporation (BBC, in the public sector), and Mind charity (in the voluntary sector). For each organisation, the report details their size, scope, mission, vision, stakeholders, and legal structure. Finally, the report explores key functions within a business, using Boohoo as an example, highlighting the roles of Human Resources, Finance, Marketing, and IT/Technology and how they interrelate to ensure smooth business operations.
