Business involves organized efforts by enterprises to supply goods and services to consumers for profit. It has multiple goals including profit, growth, customer satisfaction, and service to society. Business is characterized by constant change, large size, diversification, globalization, new technology, and intense competition. Both internal factors like management structure and external factors like government regulations and the economic environment influence business decisions. The external environment consists of micro factors like suppliers, customers and competitors, and macro factors like economic conditions, socio-cultural trends, and government policies, which are beyond a firm's control but impact its operations. Understanding both the internal and external business environment is crucial for strategic decision making.
