which they then sell at a profit. Companies that make physical goods, such as cars or pipes, are considered manufacturers. Real estate businesses generate profit from the selling, renting, and development of properties comprising land, residential homes, and other kinds of buildings. Retailers and distributors act as middle-men in getting goods produced by manufacturers to the intended consumer, generating a profit as a result of providing sales or distribution services. Most consumer-oriented stores and catalog companies are distributors or retailers. Service businesses offer intangible goods or services and typically generate a profit by charging for labor or other services provided to government, other businesses, or consumers. Organizations ranging from house decorators to consulting firms, restaurants, and even entertainers are types of service businesses. Transportation businesses deliver goods and individuals from location to location, generating a profit on the transportation costs. Utilities produce public services such as electricity or sewage treatment, usually under a government charter. There are many other divisions and subdivisions of businesses. The authoritative list of business types for North America is generally considered to be the North American Industry Classification System, or NAICS. The equivalent European Union list is the Statistical Classification of Economic Activities in the European Community (NACE).Mill, [edit] Management Main article: Management The efficient and effective operation of a business, and study of this subject, is called management. The major branches of management are financial management, marketing management, human resource management, strategic management, production management, operations management, service management and information technology management.[citation needed] Owners engage in business administration either directly or indirectly through the employment of managers. Owner managers, or hired managers administer to three component resources that constitute the business' value or worth: financial resources, capital or tangible resources, and human resources. These resources are administered to in at least five functional areas: legal contracting, manufacturing or service production, marketing, accounting, financing, and human resourcing.[citation needed] [edit] Reforming state enterprises In recent decades, assets and enterprises that were run by various states have been modeled after business enterprises. In 2003, the People's Republic of China reformed 80% of its state-owned enterprises and modeled them on a company-type management system.[2] Many state institutions and enterprises in China and Russia have been transformed into joint-stock companies, with part of their shares being listed on public stock markets. Business process management (BPM) is a holistic management approach[1] focused on aligning all aspects of an organization with the wants and needs of clients. It promotes business effectiveness and efficiency while striving for innovation, flexibility, and integration with technology. BPM attempts to improve processes continuously. It can therefore be described as a "process optimization process." It is argued that BPM enables organizations to be more efficient, more effective and more capable of change than a functionally focused, traditional hierarchical management approach.
