A business management degree prepares students for a career in business, which may stretch across any sector or industry. Their career options are therefore varied. Industries as diverse as chemicals, utilities, fashion, health, grocery and construction all require functional managers with a clear understanding of systems, efficiency and operational issues. Opportunities exist in management and analysis roles with employers in the private, public and voluntary sectors. Graduate training schemes offered by large employers frequently focus on commercial roles. Many give experience in several departments but others encourage specialization from the outset. Studying for a business management degree allows one to develop a broad understanding of business organizations and provides them with subject-specific knowledge in areas such as markets, customers, finance, operations, communication, information technology and business policy and strategy. Business issues are often addressed at a European and international level. Some graduates choose to undertake further study in subjects such as marketing, finance, human resources, computing and international business management, in order to develop their expertise in a particular area of business. Those combining study with a job often work towards a professional qualification, usually supported by their employer.
